Description: The present invention relates to certain novel beta-aminoethyl-substituted phenyl compounds, especially beta-aminoethoxy-substituted phenyl compounds, which are effective as anti-inflammatory and/or analgesic agents. This invention also relates to methods for synthesizing compounds of the present invention, and intermediates useful in these synthesis methods. The present invention further relates to pharmaceutical compositions containing these compounds, which compositions are useful for treating diseases involving inflammation and/or pain. Finally, the present invention relates to methods for treating diseases characterized by inflammation or pain. Inflammation, or the "inflammatory response", is the result of complex interconnected physiological events, including increased vascular permeability, fluid accumulations, and the migration of a changing population of inflammatory cells into the inflamed area. The clinical manifestations of inflammation include swelling (edema), increased local temperature, erythema, and pain. The inflammatory response can be triggered by any of a number of causative factors, including certain bacteria, radiation, hypersensitivity to chemical agents, arthritis-like conditions, and the like. The inflammatory response is generally believed to be a primary defense mechanism in the body, but, unchecked, can become excessive and can result in functional impairment. The use of non-steroidal anti-inflammatory, anti-pyretic and analgesic drugs, especially the salicylates, which include aspirin and aspirin derivatives, to combat inflammation and attendant pain is accepted medical practice. The non-steroidals are commonly employed to relieve pain and inflammation associated with, for example, bursitis, arthritis, and the like. While pain is incapable of precise definition due to its basically subjective nature, it can generally be said that the term refers to feelings of distress or suffering caused by stimulation of specialized nerve endings. A great variety of drugs have been developed to reduce pain in man and other animals; some directed to eliminating pain at its source, and others directed to blocking the assimilation of pain by the brain. Among the latter group of drugs that are designed to block the sensation of pain, are the analgesics, which generally relieve pain without causing unconsciousness. Analgesics can be further classified in two main categories: opioid analgesics, including morphine, codeine, levorphanol, and the morphine-like analgesics meperidine, and methadone; and antipyretic analgesics, such as aspirin, ibuprofen, phenacetin, acetaminophen, phenylbutazone, and indomethacin. Although the precise pharmacological action of these analgesics is uncertain, there are certain effects which readily distinguish the opioid analgesics from the antipyretics. In particular, the antipyretics are weak analgesics, with much of their effect in the peripheral nervous system, so that behavioral changes do not usually occur. Generally, these analgesics relieve only somatic pain originating from muscles, joints, tendons and fasciae, and are ineffective against deep visceral pain. However, the opioid analgesics are quite effective against all types of pain, with broad-based action in the central nervous system. Aside from potent analgesia, the opioids, also known as narcotics, often produce effects on mood and other behavioural changes. Perhaps the most notable side effect of the opioid analgesics is the fact that their repeated use is associated with tolerance, as well as psychic and physical dependence. It has been recently discovered that capsaicin, a natural product of certain species of the genus Capsicium , induces analgesia. Capsaicin (trans-8-methyl-N-vanillyl-6-nonenamide) and "synthetic" capsaicin (N-vanillylnonanamide) are disclosed as analgesics in U.S. Patent 4,313,958, LaHann, issued February 2, 1982.

The disclosures of all these patent specifications and articles are incorporated herein by reference in their entirety. Notwithstanding the great effort already put forth to identify anti-inflammatory and analgesic agents, there remains a continuing need to identify new compounds and compositions which are effective for treating inflammation and/or pain. The compounds of the present invention are particularly useful for such purposes since systemic doses of these compounds can be administered to produce general analgesia and anti-inflammatory effects; or local doses can be administered to produce a local analgesic effect similar to that obtained with known local anesthetics. The opiate analgesics and antipyretic analgesics which are presently widely used for general analgesia are typically not effective via local administration and thus are not generaly used as local anesthetics. In addition, the compounds of the present invention are superior to known local anesthetics since they produce analgesia without the loss of mechanical sensation (i.e., "numbing") or motor coordination which are typically observed with the use of known local anesthetics. The properties of the compounds of the present invention therefore make these compounds uniquely suited for local administration before, during and/or after local surgical operations, such as oral surgeries and minor orthopedic surgeries. An object of the present invention is therefore to provide compounds which can be administered to produce general analgesia and/or anti-inflammatory effects, or can be administered to produce local anesthesia without the associated negatives (e.g., numbness; loss of motor coordination) typically observed with known local anesthetics. Another object of the present invention is to provide compounds which are effective anti-inflammatory and/or analgesic agents, as well as pharmaceutical compositions containing these compounds. It is the further object of the present invention to provide methods for treating diseases characterized by inflammation or pain. A still further object of the present invention is to provide compounds, and compositions containing these compounds, which have high efficacy, high potency, and/or good therapeutic indices. An additional object is to provide compounds and compositions which cause very little or no skin irritation when administered topically. In addition, an object of the present invention is to provide compounds which are easily formulated and/or dosed. Another object is to provide compounds which are substantially water soluble. The present invention also relates to methods for synthesizing compounds of the present invention which give high yields and/or which are inexpensive; and to intermediates useful in these synthesis methods. These and other objects will become readily apparent from the detailed description which follows. All percentages and ratios used herein are by weight unless otherwise specified.

The present invention further relates to methods for synthesizing the beta-aminoethoxy-substituted phenyl compounds of the present invention. One method comprises the steps of : (1) reacting a specific phenol compound with a specific vicinal dihalide (preferably a vicinal dibromide) to form a beta-haloethoxy phenyl compound; followed by (2) reacting the beta-haloethoxy phenyl compound with an azide salt (preferably sodium azide) to form a beta-azidoethoxy phenyl compound; followed by (3) reducing the azido moiety (preferably with SnCl₂) to form the beta-aminoethoxy phenyl compound. The present invention also relates to the novel beta-haloethoxy phenyl compounds and novel beta-azidoethoxy phenyl compounds which are useful intermediates in this synthesis method. Another synthesis method comprises the steps of (1) reacting a specific phenyl compound with a phthalimide salt (preferably a potassium phthalimide salt) to form a beta-phthalimidoethoxy phenyl compound; followed by (2) removing the phthalimido moiety with hydrazine to give the beta-aminoethoxy phenyl compound. The present invention also relates to the novel beta-phthalimidoethoxy phenyl compounds which are useful intermediates in this synthesis method. Another synthesis method comprises the steps of (1) reacting a specific phenol compound (preferably as its phenolic anion) with a specific aziridine compound to form a nitrogen-substituted beta-aminoethoxy phenyl compound; followed by (2) reducing the nitrogen substituent off of the nitrogen-substituted beta-aminoethoxy phenyl compound (preferably with sodium metal in liquid ammonia) to form the beta-aminoethoxy phenyl compound. DETAILED DESCRIPTION OF THE INVENTION Analgesic and/or Anti-inflammatory Agents The compounds useful in the present invention are beta-aminoethyl-substituted phenyl compounds, and the pharmaceutically-acceptable salts and amides thereof, which are effective as anti-inflammatory and/or analgesic agents, having the general structure: In this general structure, the W-X moiety is selected from -C(O)NH-, -C(S)NH-, -S(O)₂NH-, -NHC(O)O-, -NHC(S)O-, -NHC(O)NH- and -NHC(S)NH-.

In order to determine and assess pharmacological activity, testing of these compounds in animals is carried out using various assays known to those skilled in the art. Thus, analgesic activity may be tested in art-known models such as the acetylcholine and phenylquinone models in mice, the Randall-Selitto model in rats, and the hot-plate test in mice and rats. The anti-inflammatory activity of the compounds can be conveniently demonstrated using an assay designed to test the ability of these compounds to antagonize the local edema which is characteristic of the inflammatory response. Examples of such known tests include the carrageenan rat edema test, the oxazolone-induced inflamed mouse ear test, and the arachidonic acid-induced inflamed mouse ear test. Another useful art-known test is the adjuvant arthritis test.

Certain of these tests for pharmacological activity are also described in more detail in the Examples provided hereinafter. As noted hereinbefore, capsaicin and a wide variety of other substituted phenyl compounds are known to have analgesic and/or anti-inflammatory activity. Typically, however, these compounds are very difficult to formulate and dose due to insolubility in water. Attempts to improve water solubility for these types of compounds, for example by adding certain hydrophilic substituents to the phenyl ring, results in compounds which are not efficacious. Surprisingly, however, the beta-aminoethyl-substituted phenyl compounds of the present invention (which are chemically very similar to non-efficacious compounds having hydrophilic substituents) are substantially water soluble and are efficacious as analgesic and/or anti-inflammatory agents. In addition, relative to the previously disclosed capsaicinoid and phenylacetamide compounds which have demonstrated analgesic and/or anti-inflammatory activity, the compounds of the present invention are substantially more water soluble, are more efficacious and/or more potent particularly when administered orally, and are generally less iritating to skin. The compounds of the present invention are prepared from readily-available materials. Techniques useful for the preparation of the present compounds, and starting materials for the preparation of the present compounds, are described in U.S. Patent 4,313,958, LaHann, issued February 2, 1982; U.S. Patent 4,238,505, Nelson, issued December 9, 1980; European Patent Application 0089710, LaHann, et al., published September 28, 1983; U.S. Patent 4,401,663, Buckwalter, et al., issued August 30, 1983; U.S. Patent 4,424,205.

Representative procedures for synthesizing compounds of the present invention are provided hereinafter. The compounds of the present invention typically comprise from 0.00001% to 99.9% by weight of the pharmaceutical compositions of the present invention, preferably from 0.0001% to 50%, and most preferably from 0.0001% to 25%. Pharmaceutically-acceptable Carrier In addition to the pharmaceutical agent as described hereinbefore, the pharmaceutical compositions of the present invention essentially comprise a pharmaceutically-acceptable carrier. The term "pharmaceutically-acceptable carrier", as used herein, means one or more compatible solid or liquid filler diluents or encapsulating substances which are suitable for administration to a human or lower animal. The term "compatible", as used herein, means that the components of the pharmaceutical compositions are capable of being commingled with the compound of the present invention, and with each other, in a manner such that there is no interaction which would substantially reduce the pharmaceutical efficacy of the pharmaceutical composition under ordinary use situations. Pharmaceutically-acceptable carriers must, of course, be of sufficiently high purity and sufficiently low toxicity to render them suitable for administration to the human or lower animal being treated. Some examples of substances which can serve as pharmaceutically-acceptable carriers are sugars such as lactose, glucose and sucrose; starches such as corn starch and potato starch; cellulose and its derivatives, such as sodium carboxymethylcellulose, ethylcellulose, cellulose acetate; powdered tragacanth; malt; gelatin; talc; stearic acid; magnesium stearate; calcium sulfate; vegetable oils such a peanut oil, cottonseed oil, sesame oil, olive oil, corn oil and oil of theobroma; polyols such as propylene glycol, glycerine, sorbitol, mannitol, and polyethylene glycol; sugar; alginic acid; pyrogen-free water; isotonic saline; phosphate buffer solutions; cocoa butter (suppository base); emulsifiers, such as the Tweens®; as well as other non-toxic compatible substances used in pharmaceutical formulations. Wetting agents and lubricants such as sodium lauryl sulfate, as well as coloring agents, flavoring agents, excipients, tableting agents, stabilizers, antioxidants, and preservatives, can also be present. Other compatible pharmaceutical additives and actives (e.g., NSAI drugs; pain killers; muscle relaxants) may be included in the pharmaceutically-acceptable carrier for use in the compositions of the present invention. For example, art-known local anaesthetics may be included in the pharmaceutically-acceptable carrier (e.g., benzyl alcohol; Novocaine®; lidocaine). The choice of a pharmaceutically-acceptable carrier to be used in conjunction with the compounds of the present invention is basically determined by the way the compound is to be administered. The preferred modes of administering the compounds of the present invention are by injection, orally and topically. If the compound is to be injected, the preferred pharmaceutically-acceptable carrier is sterile, physiological saline, the pH of which has been adjusted to about 4. Suitable pharmaceutically-acceptable carriers for topical application include those suited for use in creams, gels, tapes and the like; and for oral administration include those suited for tablets and capsules. The pharmaceutically-acceptable carrier employed in conjunction with the compounds of the present invention is used at a concentration sufficient to provide a practical size to dosage relationship. The pharmaceutically-acceptable carriers, in total, may comprise from 0.1% to 99.99999% by weight of the pharmaceutical compositions of the present invention, preferably from 50% to 99.9999%, and most preferably from 75% to 99.9999%. Total single dosages of the compounds of the present invention present in pharmaceutical compositions herein are generally from 1 µg to 10 g. Preferred single dosages are from 1 µg to 3500 mg; more preferred are from about 1 µg to 1000 mg; and most preferred are from about 1 µg to 600 mg. Specific oral, topical, and injectable formulations useful in this invention are described in the following U.S. Patents , all incorporated by reference herein: U.S. Patent No. 4,401,663, Buckwalter, et al, issued August 30, 1983; U.S. Patent No. 4,424,205, LaHann, et al, issued January 31, 1984; U.S. Patent No. 4,443,473, Buckwalter, et al, issued April 12, 1984; U.S. Patent No. 4,493,848, LaHann, et al, issued January 15, 1984.

The preferred dosage form for topical administration is a lotion comprising a safe and effective amount of the analgesic agent of the present invention, which is preferably a concentration of from 0.01 mg/ml to 10 mg/ml, more preferably from 0.1 mg/ml to 5 mg/ml, and most preferably from 0.5 mg/ml to 2 mg/ml. While topical application is preferably utilized to produce localized analgesic effects, systemic efforts can also be achieved by utilizing larger dosages of the topical compositions and/or greater surface area coverage. C. Injectable Dose Forms The compounds of the present invention are also useful when injected. The dosage of the compound of the present invention which is both safe and effective to provide analgesic or antiirritant activity will vary with the particular condition being treated, the severity of the condition, the duration of treatment, the specific compound employed and its usage concentration, and like factors within the specific knowledge and expertise of the attending physician and commensurate with a reasonable benefit/risk ratio associated with the use of any drug compound. In addition, lower dosages will be utilized when only local analgesia is desired, whereas higher dosages will be utilized when general analgesia is desired. The injectable dosages and dosage ranges given herein are based on delivery of the compound of the present invention to a 70 kg human and can be adjusted to provide equivalent dosages for patients of different body weights. Methods and materials for manufacturing injectables can be found in Remington's Pharmaceutical Sciences , 17ed., 1985, Chapter 85, p. 1518, the disclosures of which are incorporated herein by reference in their entirety. Materials for use in injectables are also described more fully hereinafter. Generally, three types of injectable dosage forms are preferred: 1) aqueous solutions; 2) non-aqueous solutions; and 3) emulsions. The above dosage forms typically contain from 0.001 mg/ml to 10 mg/ml, preferably from 0.1 mg/ml to 1 mg/ml, more preferably from 0.4 mg/ml to about 0.6 mg/ml. The aqueous solutions preferably consist of water (preferably from 80% to 90%), a suitable solubilizer, various types of acids, and an antimicrobial agent. Several solubilizers are known. Examples of such solubilizers are as follows: urea compounds (e.g., urea; urethan); surfactants (e.g., Tweens; Spans; sodium deoxycholate and Pluronics); cellulosic agents (e.g., carboxymethylcellulose); carbohydrates (e.g., Sorbit; Mannitol); B vitamins (e.g., nicotinamide); xanthine derivatives; and alcohols (e.g., benzyl alcohol). Examples of acids to be used include the following: glucouronic; galactouronic; fumaric; gentisic; acetic; citric and lactobionic. Types of antimicrobial agents that can be used are the following: phenylmercuric nitrate; thimerosal; benzethonium chloride; benzalkonium chloride; phenol; cresol; and chlorobutanol. An art-known local anesthetic (e.g., benzyl alcohol; Novocaine®; lidocaine) may also be included. Non-aqueous solutions can comprise solvents which are either miscible with water or immiscible with water. Non-aqueous solvents miscible with water are mixed with water to yield a concentration preferably between from 5% to 90%. Examples of typical non-aqueous solvents miscible with water include: solvents used at 100% (e.g., propylene glycol; polyethylene glycol; dimethylformamide; dimethylacetamide); solvents mixed with water to yield a concentration of between from 5% to 90% (e.g., ethanol; glycerin; butylene glycol; tetraglycol; dimethylacetamide; dimethylformamide; lactic acid; ethyl acetate; N-B-hydroxyethyl lactamide; tetraethylurea; acetone; sulfolane; isopropylene glycol ether; hexenyl glycol; diethylene glycol dimethyl ether; tetrahydrofurfuryl methyl ether; N.N-dimethylmethoxyacetamide). Non-aqueous solvents not miscible with water are primarily vegetable oils. Some common lipid solvents not miscible with water for injectable compositions are sesame oil, olive oil, arachis oil, maize oil, almond oil, cottonseed oil, caster oil, ethyl oleate, ethyl carbonate and isopropyl myristate. Emulsions can be of either the water-in-oil (W/O) or the oil-in-water (O/W) type. Typical oils are listed hereinbefore. The continuous phase is preferably about 99% of the formulation while the discontinuous phase is preferably about 1% of the formulation. Emulsifiers and stabilizers are typically used to complete the formulation. Examples of typical emulsifying agents are: surface active agents (e.g., sodium deoxycholate; Span; Tween); and natural surface active agents (e.g., Sorbit; phosphatidylcholine). Injectable dose forms for producing general analgesia typically comprise from 0.1 mg to 1000 mg, and preferably from 0.5 of to 700 mg, of the compound of the present invention. Injectable dose forms for producing local analgesia typically comprise from 1 µg to 500 µg of the compound of the present invention. Methods for Producing Anti-Inflammatory Activity and Analgesia The present invention also encompasses methods of producing anti-inflammatory activity and/or analgesia (either general analgesia or local analgesia) in humans or lower animals through administering, to the human or lower animal in need of such treatment, a safe and effective amount of a compound of the present invention. This amount can be given in a single dose or multiple doses repeatedly over the course of the treatment. While dosages higher than those described hereinbefore are effective to reduce inflammation and produce analgesia, care must be taken in some individuals to prevent adverse side effects. The compounds and compositions of this invention can be used to treat and prevent pain, to provide analgesia, and/or to reduce inflammation in various disorders at the deeper structures, muscles, tendons, bursa and joints associated with disease and trauma, and in various other conditions in which non-steroidal anti-inflammatory, antipyretic and analgesic drugs, such as aspirin, and opioids, such as morphine, have heretofore been used to alleviate pain and discomfort and reduce inflammation. The preferred modes of administration are orally, topically, and by injection, including, e.g., dermatomucosally (for example, dermally, rectally and the like) and parenterally (for example, by subcutaneous injection, intramuscular injection, intra-articular injection, intravenous injection and the like). Ocular administration and inhalation is also included. Thus, specific modes of administration include, without limitation, oral, transdermal, mucosal, sublingual, intramuscular, intravenous, intraperitoneal, and subcutaneous administration, as well as topical application. The phrase "safe and effective amount", as used herein, means an amount of a compound or composition high enough to significantly positively modify the condition to be treated, but low enough to avoid serious side effects (at a reasonable benefit/risk ratio), within the scope of sound medical judgment. The safe and effective amount of the compound or composition will vary with the particular condition being treated, the age and physical condition of the patient being treated, the severity of the condition, the duration of the treatment, the nature of concurrent therapy, the specific analgesic agent employed, the particular pharmaceutically-acceptable carrier utilized, whether general or local analgesia is desired, and like factors within the knowledge and expertise of the attending physician. However, daily dosages can range from 0.1 mg/kg of body weight to 500 mg/kg of body weight. Preferred daily dosages are from 1 to about 100 mg/kg of body weight. Up to 6 single dosages per day may be administered. Topical administration can be used to reduce inflammation and produce local or systemic analgesia, through directly laying on or spreading a safe and effective amount of the compound or composition of the present invention on epidermal or epithelial tissue, including outer skin and oral, gingival, and nasal tissue. The amount of the pharmaceutical composition to be topically administered may vary from 0.01 mg/cm² to 5 mg/cm², and if a patch is worn over the affected area possibly higher concentrations, depending upon such factors as the sensitivity, type and location of tissue to be treated, the composition and carrier (if any) to be administered, and the particular compound to be administered as well as the particular disorder to be treated and the extent to which systemic (as distinguished from local) effects are desired. The extent of systemic analgesia also depends upon such factors as the amount of compound, the area of tissue to be covered, and the ability of the compound to penetrate the skin tissue. Oral administration can be used to reduce inflammation and produce analgesia through oral dosing of a pharmaceutical composition comprised of a safe and effective amount of the compound of the present invention in a suitable oral pharmaceutical carrier. The compound is absorbed by the gastrointestinal tract. The pharmaceutical composition may consist of solid dosage forms such as tablets, hard gelatin capsules, soft gelatin capsules, bulk powders, and microcapsules of the drug. Alternately, it may consist of a liquid dosage form such as an aqueous or nonaqueous solution, emulsion, or suspension. The amount of the compound ingested depends upon the bioavailability of the compound from the oral pharmaceutical composition. Typically, however, the compounds of the present invention are dosed in an amount of from 0.1 mg/kg of body weight to 500 mg/kg, and preferably from 1 to 100 mg/kg of body weight. The amount of the pharmaceutical composition depends upon the percent of compound within its formula, which is a function of the amount of the compound required per dose, its stability, release characteristics and other pharmaceutical parameters. Generally, the oral pharmaceutical composition should comprise from 5% to 50% of the compound of the present invention. The preferred method of injectable administration is via a sterile aqueous solution of pH from 3 to 8 (more preferred is pH of from 3 to 6) or as a sterile emulsion. Larger amounts of drug can be administered to produce systemic analgesia using doses in the range of 0.01 to 10.0 mg/kg; however, smaller amounts of the drug can be administered via injection to produce a local analgesic and/or anti-inflammatory effect. The smaller quantities of drug to be administered are typically in the range of from about 1 to about 500 ug/injection; these amounts are used to produce a local analgesic effect without the numbing affect commonly associated with a local anesthetic. Such low doses avoid any significant systemic exposure to the drug and thereby greatly reduce the possibility of side effects. These local administrations may be useful for the treatment of pain and inflammation associated with minor surgical procedures, e.g., minor oral surgeries, tooth extractions, etc., or minor orthopedic surgeries. The preferred modes of administration for producing local analgesia are interdermally, subcutaneously, percutaneously, and intramuscularly. Systemic administration can also be used to reduce inflammation and produce general analgesia. Such administration may be intravenously, intramuscularly, or subcutaneously. The amount of pharmaceutical composition typically administered may vary from 0.5 to 5 ml of a solution or suspension of the compound of the present invention in a pharmaceutically-acceptable carrier in a single dose. These compositions may also be administered systemically in multiple dosages, or by infusion.

The following Examples further describe and demonstrate the preferred embodiments within the scope of the present invention. The Examples are given solely for the purpose of illustration. All temperature readings are in °C. EXAMPLE I Synthesis of N-((4-(2-aminoethoxy)-3-methoxyphenyl)-methyl)-nonanamide To a flame dried 5L, 3 neck, round bottom flask is added N-vanillylnonanamide (20.9 g; 71.3 millimole; which is disclosed in U.S. Patent 4,313,958, to LaHann, issued February 2, 1982, incorporated by reference in its entirety herein), hexamethylphosphoramide (49.65 mL) and 2830 mL of dimethylformamide. After dissolving at room temperature with mechanical stirring, potassium tert-butoxide (28 g; 249.7 millimole) is added with stirring. A solution containing (N-trifluoroacetyl)-2-bromo-aminoethane (17.3 g; 78.5 millimole) in 170 mL of dimethylformamide is added dropwise over a period of 1 hour to the mixture described above with continuous stirring. The reaction mixture is then heated to 80°C in an oil bath for 18 hours, after which time it is allowed to cool to room temperature. The reaction mixture is then concentrated to a volume of approximately 200 mL under vacuum. The concentrated residue is diluted to 6L with diethyl ether and washed successively with 2 x 4 L of 0.5 N HCl, 2 x 4 L of water, and 500 mL of saturated sodium chloride. The ether layer is dried over magnesium sulfate and evaporated to a white solid. The white solid product is recrystallized from ether to yield 10.07 g of the desired product N-((4-(2-(N′-trifluoroacetyl)-aminoethoxy)-3-methoxyphenyl)-methyl)-nonanamide (yield 32%). The N-((4-(2-(N′-trifluoroacetyl)-aminoethoxy)-3-methoxy-phenyl)methyl)-nonanamide (10.07 g) is dissolved in 400 mL of ethanol, and 23.2 mL of 2.5 N sodium hydroxide is added. The reaction is stirred at room temperature for 2 hours and then diluted with 2 L of water. The aqueous mixture is extracted with ethyl acetate (4 x 500 mL), and the ethyl acetate extracts are combined, washed with saturated sodium chloride, and dried over anhydrous sodium sulfate. The ethyl acetate solution is concentrated to yield 7.7g of solid product which is purified as follows. The crude product is dissolved in 70 mL of warm chloroform and loaded onto a silica gel column. The column is eluted under reduced presure (aspirator) with 2700 mL of chloroform and the eluant is discarded. The column is then eluted with 1500 mL of a solvent mixture containing chloroform 93%, triethylamine 2%, and methanol 5%. This second eluant is collected, concentrated, and then dried to yield 6.86 g of white solid product N-((4-(2-amino-ethoxy)-3-methoxyphenyl)-methyl)-nonanamide (yield 88%). m.p. = 118-119°C; ¹H-NMR (CDCl₃): 0.97 (3H, t), 1.2-2.0 (14H, m), 2.25 (2H, t), 3.17 (2H, t), 3.9 (3H, s), 4.15 (2H, t), 4.45 (2H, d), 6.0 (1H, m), 6.85 (3H, br s, aromatic).

The disappearance of starting material is monitored by TLC (6% acetone/CH₂Cl₂). After the reaction is completed (typically after reacting overnight), the solution is diluted with CHCl₃ (500 ml), washed three times with water and aqueous washings are then combined and extracted once with CHCl₃ (250 ml). The organic phases are combined, washed with 10% H₃PO₄ (250 ml), saturated NaHCO₃ (250 ml), brine, then dried (MgSO₄) and filtered. The volume is reduced to less than 500 ml by vacuum distillation and the liquid is then transferred to a 4-L flask. After cooling to approximately 10°C, Et₂O (2L) is added and the flask is cooled in an ice bath. A white precipitate forms and additional Et₂O is added to make a volume of 4 l. The thick amorphous solid is filtered, washed with Et₂O, dried and used without further purification.

The solution is heated to a gentle reflux for 24 hours. The solution is transferred to a 6L separatory funnel using 2 L of EtAc to wash the inorganic residue. The solution is then extracted with water (2L), 10% H₃PO₄ (1 L), saturated NaHCO₃ (1 L), dried (MgSO₄) and concentrated to give 156 gm (92%) of a white solid. Purification is accomplished using a Waters prep 500 HPLC (two columns) eluting with CHCl₃ to give 146 gm (86%) of pure azide.

(c) Synthesis of N-((4-(2-aminoethoxy)-3-methoxyphenyl)methyl)- 9Z-octadecenamide: N-((4-(2-azidoethoxy)-3-methoxyphenyl)-methyl)-9Z-octadecenamide (139 gm, 0.286 mole) is added to MeOH (1 L) in a 2L flask. The mixture is warmed to dissolve all the substrate. Stannous chloride dihydrate (97 gm, 0.43 mole) is ground in a mortar and pestle and delivered all at once to the reaction solution. The flask is then fitted with a short Vigreux column and a bubbler to monitor gas evolution. The pale yellow-green solution warms and gives a steady evolution of gas for 20 minutes. The reaction is stirred a total of one hour. The content of the reaction vessel is poured into a 2L graduated cylinder and fresh MeOH is added until the volume is 2L. One-half of this solution is worked up at a time. 1L of the reaction solution is placed in a 6L separator funnel and 1 N NaOH (1L) is added, immediately forming a thick cheese-like precipitate. Na₂SO₄ (50 gm) is added and the mixture is vigorously shaken for five minutes. To the suspension is added EtAc (2L) and the solution shaken until two layers form. 1200 ml of the aqueous phase is removed, H₂O (500 ml) is added and the solution is reshaken. The aqueous layers are then combined and extracted with EtAc (1L). All the organic layers are combined, dried (MgSO₄), filtered and concentrated to give 125 gm (95%) of white solid. Purification is accomplished on a Waters Prep 500 HPLC (2 columns) by first equilibrating and eluting with CHCl₃ until nonpolar impurities are removed (8 L CHCl₃), then by eluting with CHCl₃/MeOH/triethylamine (94:3:3; 4L). The various fractions are analyzed by TLC using butanol/acetic acid/ H₂O (4:1:1); ninhydrin is used to develop the product spots.

EXAMPLE III Synthesis of N-((4-(2-aminoethoxy)-3-methoxyphenyl)-methyl)-9Z-octadecenamide by the Phthalimide Synthesis Method (a) Synthesis of N-((4-(2-bromoethoxy)-3-methoxyphenyl)-methyl)-9Z-octadecenamide is accomplished following the same procedure as described in Example II. (b) Synthesis of N-((4-(2-phthalimidoethoxy)-3-methoxy-phenyl)methyl)-9Z-octadecenamide: N-((4-(2-bromoethoxy)-3-methoxyphenyl)-methyl)-9Z-octadecenamide (615.5 gm, 1.17 moles) and DMF are combined in a 5 L flask equipped with a mechanical stirrer and a thermometer. The mixture is stirred and heated to 55°C. Once the solution becomes homogeneous, potassium phthalimide (270.0 gm, 1.47 mole) is added and the solution is maintained at 55°C with good stirring. After ca. 10 minutes the reaction solution becomes homogeneous. Precipitation of a white solid then begins and the reaction is allowed to stir overnight at 55°C. TLC (acetone/dichloromethane 6:94) indicates when the starting material has been consumed. The reaction solution is divided into three equal volumes and each is worked up as follows: The solution is poured into a 4 L beaker and then diluted with water to the 3500 mL mark. After standing for ca. 15 minutes the solution is divided again into two equal parts, each of which is diluted to 3500 mL with water. The white precipitate is removed by filtration and washed several times with water. The three portions are combined and dried in a vacuum oven at 90°C for 12 hours to give 682.25 g (98%) of a fine powder.

(c) Synthesis of N-((4-(2-aminoethoxy)-3-methoxyphenyl)-methyl)-9Z-octadecenamide: N-((4-(2-phthalimidoethoxy)-3-methoxyphenyl-methyl)-9Z-octadecenamide (250 gm, 0.424 mole) and ethanol (2500 mL) are combined in a 4 L beaker. The slurry is mechanically stirred and heated to 60°C. At ca. 45°C the solution becomes homogeneous. 1-Hexene (20 mL) is added. Hydrazine hydrate (106 mL of a 64% aqueous solution) is then added. In ca. 5 minutes a white precipitate begins to form. During the 2 hour reaction time 500 mL of ethanol is added to the reaction to replenish that volume lost to evaporation. The reaction solution is then divided into three equal portions and each is worked up as follows: Methyl t-butyl ether (1.5 L) is used to transfer the slurry into a 4 L separatory funnel. Water (1 L) and 1N NaOH (500 mL) are added and the solution is thoroughly shaken. 50% NaOH (25 mL) is added and the solution is reshaken. The organic phase is then extracted twice with alkali using the same sequence, and washed with brine. The extract is dried over sodium sulfate and concentrated. The crude product is taken up in hot methyl t-butyl ether and allowed to crystallize. The crystals are filtered and dried in a vacuum desicator to give 124.87 g. A second crop of crystals, 40.82 g, is obtained to give 85% total yield.

EXAMPLE IV Synthesis of N-((4-(2-methyl-2-aminopropoxy)-3-methoxyphenyl)-methyl)-9Z-octadecenamide by the Aziridine Method To a solution of 2,2-dimethylaziridine (5.42 g; 0.076 mole; sold by Polysciences, Inc., Warrington, PA) in pyridine (100 mL) cooled in an ice bath, is added p-toluenesulfonyl chloride (21.81 g; 0.114 mole) in one portion. The reaction is stirred at 0°C for 2 hours; diluted with ether (400 mL); washed with cold 10% H₃PO₄ (2 X 150 mL), with a saturated NaHCO₃ solution (3 X 150 mL) and brine (1 X 150 mL); and dried over MgSO₄. Rotary evaporation of the solution affords a yellowish solid which is crystallized from ethyl acetate to yield the product 2,2-dimethyl-N-p-toluenesulfonyl-aziridine (4.48 g). ¹H NMR (CDCl₃): 1.53 (6H, s), 2.45 (5H, m), 7.2-8.0 ppm (4H, m, aromatics). A dispersion of KH (35% in oil; 68 mg; 0.595 mmole) is added to a dry round-bottom flask under argon and washed with n-pentane (3 x 5 mL) to remove the oil. The isolated KH is then suspended in dry DMF (5 mL) and treated in one portion with N-vanillyloleamide (248 mg; 0.595 mmole; which is prepared as described in U.S. Patent 4,493,848, to LaHann and Buckwalter, issued January 15, 1985, incorporated herein by reference in its entirety) and stirred for 1 hour at room temperature. The 2,2-dimethyl-N-p-toluenesulfonyl-aziridine (136 mg; 0.60 mmole) is then added and the resulting mixture is stirred at 50°C for 16 hours. The DMF is rotary evaporated and the residue partitioned between water and ethyl acetate (50 mL). The organic layer is washed with water (4 x 20 mL), dried over MgSO₄ and rotary evaporated to yield a light brown oil (400 mg) which is purified by using silica gel chromatography (Chromatotron, 2 mm plate, eluting with 40% ethyl acetate/hexanes) to yield the p-toluenesulfonamido-blocked intermediate as a colorless oil, (140 mg; 40%). ¹H NMR (CDCl₃): 0.93 (3H, t), 1.30 (29H, m), 2.05 (6H, m), 2.42 (3H, s), 3.65 (2H, s), 3.86 (3H, s), 4.38 (2H, d), 5.37 (2H, t), 5.7 (1H, s), 6.00 (1H, br s), 6.77 (3H, m, aromatics), 7.1-7.8 ppm (4H, m, tosyl aromatics). A solution of the p-toluenesulfonamido-blocked intermediate (2.46 g; 3.8 mmoles) in dry THF (10 mL) is stirred at -60°C under argon and treated with freshly condensed NH₃ until a final volume of 20 mL is achieved. This solution is then allowed to reflux gently under a dry ice condenser while small flakes of freshly cut sodium are slowly added. When a blue color persists for more than 5 minutes without the addition of more sodium, the reaction is quenched by the addition of solid ammonium acetate and evaporated under a gentle stream of nitrogen. The remaining solid is then partitioned between ether (500 mL) and NaOH solution (1N, 200 mL). The organic layer is washed with water (2 x 100 mL), dried over Na₂SO₄, and rotary evaporated to yield crude N-((4-(2-methyl-2-aminopropoxy)-3-methoxyphenyl)-methyl)- 9Z-octadecenamide (1.75 g). This yellowish oil is purified using silica gel column chromatography eluting first with ethyl acetate to remove nonpolar impurities, then with methanol/methylene chloride (50%) to bring off the amine (1.1 g; 59%). ¹H NMR (CDCl₃): 0.90 (3H, t), 1.23 (6H, s), 1.30 (22H, s), 1.87 (2H, s), 2.10 (6H, m), 3.73 (2H, s) 4.38 (2H, d), 5.38 (2H, t, alkene), 5.93 (1H, br s), 6.83 ppm (3H, s, aromatic). ¹³C NMR (CDCl₃): 13.77, 22.35, 25.51, 26.05, 26.88, 28.97, 31.53, 36.24, 42.74, 49.77, 55.67, 79.09, 111.86, 113.95, 119.73, 129.32, 129.56, 131.71, 147.91, 149.58, 172.76 ppm. EXAMPLE V Carrageenan Rat Paw Edema Test Compounds of the present invention are tested for anti-inflammatory activity using the Carrageenan Rat Paw Edema Test. Male Sprague Dawley rats (Charles River Breeding Laboratories Inc.) are weighed and food fasted overnight. The animals are divided into four to six groups of six animals each according to body weights, average about 145 g, so that each group has about the same average weight (within 10 g). The following morning five ml of water is dosed orally via stomach tube to each animal to facilitate paw swelling. Thirty minutes later the animals are dosed with the test compound and then placed in individual cages. The compound of the present invention is dissolved in distilled deionized water with 1 equivalent of 1 N acetic acid and delivered via stomach tube in 1 ml volume. One hour after dosing the test compound, the animals are placed in a plastic restrainer and 50 ul of a 1% (w/w) carrageenan solution in 0.9% saline is injected into the ventral surface of the left rear paw. Paw volumes (0 time) are determined on both hind paws with a mercury displacement device equipped with a transducer and digitizer following the carrageenan injection. Four hours after the carrageenan injection, the paw volumes are again determined. The results are expressed as percent inhibition of the mean paw volume of the test group relative to the control group according to the formula: (C - T a..n)/C x 100 = Percent Inhibition where C is the average difference in paw volume before and after carrageenan-induced swelling, and Ta..n is the difference in paw swelling in the treated animals (a..n). Statistical differences are determined by one way analysis of variance. The compound N-((4-(2-aminoethoxy)-3-methoxyphenyl)-methyl)-9Z-octadecenamide of the present invention has the following anti-inflammatory activity: Example VI Rodent Hot Plate Test The degree of thermal analgesia obtained is determined using the "rodent hot plate test" (RHP). The RHP system is designed to detect and evaluate agents which elevate the threshold for the perception of pain. Classically, this method has been utilized primarily to evaluate opioid (narcotic) analgesic agents, such as morphine. Unless administered in toxic quantities, antipyretic analgesics, such as aspirin or acetaminophen, exhibit little or no activity in the RHP system. Male Sprague-Dawley rats (Charles River Breeding Laboratories Inc.) weighing between 100 and 125 grams upon arrival are used to evaluate the compounds of the present invention. Animals are double housed in stainless steel cages, and are fed Purina Rat Chow and tap water ad libitum . The animals are food fasted the afternoon proceeding the day of the study, and food is returned 5 hours post-treatment. Animals not being dosed by oral gavage are not fasted. The apparatus for evaluating analgesic activity consists of an insulated copper hot plate whose surface is maintained at 55 ± 0.5°C by a circulating water bath. A bottomless glass container (12" (30 cm) tall by 8" (20 cm) diameter) is used to restrict the animal to a defined area of the hot plate. After dosing, the animal is placed through the top opening of the container, and a stop watch is started when the animal makes contact with the plate. The stop-watch is stopped upon either of the following visually observed end points: (1) licking or biting of either hind paw, or (2) jumping. If the jump is not successful but both hind paws leave the surface of the plate in an effort to jump, this is considered jumping. The stop-watch is stopped at the end point and the animal is immediately removed from the hot plate. The time (latency) between the initial contact of the animal on the hot plate and the endpoint is recorded. A 60 second cut off is used during the assay so that if the end point is not exhibited within 60 seconds, the animal is removed from the hot plate and given a score of greater than 60 seconds. Prior to dosing, animals are tested on the hot plate. This is denoted as pretest or base line latency. Usually, the animals are dosed by oral gavage, using a 1 cubic cm glass syringe connected to a size 8 french catheter. The dose volume is 5 ml/kg. On occasion, the animals are dosed by either subcutaneous administration or intravenous injection. Using the subcutaneous administration, a 1 ml tuberculin syringe is connected to a 25 gauge 5/8 inch needle, and injected under the skin in the neck or back region. For intravenous dosing, a 1 ml tuberculin syringe is connected to a 25 gauge 3/4 inch winged infusion set, and injected into the tail vein. The dose volume for subcutaneous and intravenous routes is 1 ml/kg. The latency times are typically recorded at 1.5, 3, 5, and 24 hours post-treatment. Much shorter times are recorded for an intravenous administration. The mean latency times for orally dosed compounds of the present invention are provided in Tables I, II, and III. The mean latency times for orally dosed codeine phosphate are provided in Table IV. These latency times indicate that the compounds of the present invention are potent and efficacious analgesic agents, with N-((4-(2-aminoethoxy)-3-methoxyphenyl)-methyl)-9Z-octadecenamide being at least as potent and efficacious as the known opiate codeine. EXAMPLE VII Mouse Abdominal Constriction Assay Compounds of the present invention are tested for analgesic activity using the mouse abdominal constriction assay. This assay is described in Hendershot and Forsaith, J. Pharmacol. Exp. Therapeut. , 125 , pp. 237-240 (1959); and in Methods in Narcotics Research , Ehrenpreis and Neidle, Eds. (Marcel Dekker, Inc., New York; 1975), pp. 64-65; the disclosures of both these references being incorporated in their entirety herein by reference. Male CF-1 mice (Charles River Breeding Laboratories, Inc.), weighing approximately 20 grams and food fasted overnight, are used in these assays. Test compounds are prepared for oral (p.o.) or subcutaneous (s.c.) administration, with compounds of the present invention being prepared in acidified (1 N acetic acid) distilled deionized water so that the appropriate dose is given in 0.2 mls to a 20 gram mouse. One and one half hours after administration of the test compound N-((4-(2-aminoethoxy)-3-methoxyphenyl)-methyl)-9Z-octadecenamide (p.o. or s.c.), an intraperitoneal (i.p.) injection of 0.02% phenylquinone (2.5 mg/kg) is given at a concentration of 0.25 ml/20 grams body weight. Ten minutes after the i.p. injection of phenylquinone, the number of full body writhes are counted for the succeeding ten minutes. Percent analgesia in this assay is calculated as follows: The oral dose response and subcutaneous dose response for N-((4-(2-aminoethoxy)-3-methoxyphenyl)-methyl)-9Z-octadecenamide of the present invention are provided in Table V and Table VI respectively. The oral dose response and subcutaneous dose response for N-vanillyloleamide, which is disclosed in U.S. Patent 4,493,848 to LaHann and Buckwalter, issued January 15, 1985, are provided in Table VII and Table VIII respectively. The N-vanillyloleamide is tested for analgesic activity at 3 hours post-dose rather than at 1.5 hours post-dose since this is the time at which this compound demonstrates its peak analgesic effect. The N-((4-(2-aminoethoxy)-3-methoxyphenyl)-methyl)-9Z-octadecenamide compound of the present invention is structurally the same as the N-vanillyloleamide except for the 2-aminoethoxy substitution on the phenyl ring. However, compared with the N-vanillyloeamide dosed orally, the compound of the present invention dosed orally demonstrates substantially greater analgesic potency at a substantially lower dose. EXAMPLE VIII A composition for oral administration is prepared by combining the following ingredients: N-((4-(2-aminoethoxy)-3-methoxyphenyl)-methyl)-9Z-octadecenamide 1.10 kg Sesame oil 6.50 liters The octadecenamide is dissolved in the sesame oil with the aid of sonication and is packaged in soft gelatin capsules using methods known in the art. Two of the resulting capsules, each containing 225 mg of the composition, are administered to a 60 kg human in need of treatment, producing analgesia and reducing inflammation. A substantially similar reduction of inflammation and an increased analgesic effect is obtained when the N-((4-(2-aminoethoxy)-3-methoxyphenyl)-methyl)-9Z-octadecenamide is replaced with N-((4-(2-aminoethoxy)-3-methoxyphenyl)-methyl)-nonanamide; N-((4-(2-methyl-2-aminopropoxy)-3-methoxyphenyl)-methyl)- 9Z-octadecenamide; N-((4-(2(S)-amino-3-methylbutoxy)-3-methoxyphenyl)-methyl)-9Z-octadecenamide; N-(9Z-octadecenyl)-4-(2-aminoethoxy)-3-methoxyphenylacetamide; N-octanyl-4-(2-aminoethoxy)-3-methoxyphenylacetamide; N-((4-(2-amino-3-hydroxypropoxy)-3-methoxyphenyl)-methyl)-9Z- octadecenamide; N-((4-(2-amino-2-carboxyethoxy)-3-methoxyphenyl)-methyl)-9Z-octadecenamide; and the pharmaceutically-acceptable salts and amides thereof.

One teaspoon of this formulation is administered to a 70 kg adult human, reducing inflammation and producing analgesia. A substantially similar reduction of inflammation and analgesic effect is obtained when the N-(9Z-octadecenyl)-4-(2-aminoethoxy)-3-methoxyphenylacetamide is replaced with N-((4-(2-aminoethoxy)-3-methoxyphenyl)-methyl)-9Z-octadecenamide; N-((4-(2-aminoethoxy)-3-methoxyphenyl)-methyl)-nonanamide; N-((4-(2-methyl-2-aminopropoxy)-3-methoxyphenyl)-methyl)-9Z-octadecenamide; N-((4-(2(S)-amino-3-methylbutoxy)-3-methoxyphenyl)-methyl)-9Z-octadecenamide; N-octanyl-4-(2-aminoethoxy)-3-methoxyphenylacetamide; N-((4-(2-amino-3-hydroxypropoxy)-3-methoxyphenyl)-methyl)-9Z-octadecenamide; N-((4-(2-amino-2-carboxyethoxy)-3-methoxyphenyl)-methyl)-9Z-octadecenamide; and the pharmaceutically-acceptable salts and amides thereof. EXAMPLE X A composition for topical administration is prepared by combining the following ingredients: N-((4-(2-aminoethoxy)-3-methoxyphenyl)-methyl)-9Z-octadecenamide 4 g Propylene glycol 100 ml Ethyl alcohol 100 ml The octadecenamide is dissolved in a solution containing the other ingredients. Application of 0.4 ml of the resulting liquid to a 80 cm² portion of the forearm of a 60 kg human produces local analgesia which lasts approximately two days. Little or no skin irritation is observed. A substantially similar local analgesic effect is obtained when the N-((4-(2-aminoethoxy)-3-methoxyphenyl)-methyl)-9Z-octadecenamide is replaced with N-((4-(2-aminoethoxy)-3-methoxyphenyl)-methyl)-nonanamide; N-((4-(2-methyl-2-aminopropoxy)-3-methoxyphenyl)-methyl)-9Z-octadecenamide; N-((4-(2-(S)-amino-3-methylbutoxy)-3-methoxyphenyl)-methyl)-9Z-octadecenamide; N-(9Z-octadecenyl)-4-(2-aminoethoxy)-3-methoxyphenylacetamide; N-octanyl-4-(2-aminoethoxy)-3-methoxyphenylacetamide; N-((4-(2-amino-3-hydroxypropoxy)-3-methoxyphenyl)-methyl)-9Z-octadecen amide; N-((4-(2-amino-2-carboxyethoxy)-3-methoxyphenyl)-methyl)-9Z-octadecenamide; and the pharmaceutically-acceptable salts and amides thereof. EXAMPLE XI Tablets are prepared by conventional methods, such as mixing and direct compaction, formulated as follows: One tablet is administered orally to a patient in need of analgesia two times daily to provide general analgesia. Similar results are achieved with tablets formulated as above but replacing the N-((4-(2-aminoethoxy)-3-methoxyphenyl)-methyl)-nonanamide with N-((4-(2-aminoethoxy)-3-methoxyphenyl)-methyl)-9Z-octadecenamide; N-((4-(2-methyl-2-aminopropoxy)-3-methoxyphenyl)-methyl)-9Z-octadecenamide; N-((4-(2(S)-amino-3-methylbutoxy)-3-methoxyphenyl)-methyl)-9Z-octadecenamide;N-(9Z-octadecenyl)-4-(2-aminoethoxy)-3-methoxyphenylacetamide; N-octanyl-4-(2-aminoethoxy)-3-methoxyphenylacetamide; N-((4-(2-amino-3-hydroxypropoxy)-3-methoxyphenyl)-methyl)-9Z-octadecenamide; N-((4-(2-amino-2-carboxyethoxy)-3-methoxyphenyl)-methyl)-9Z-octadecenamide; and the pharmaceutically-acceptable salts and amides thereof. EXAMPLE XII Injectable compositions are prepared as follows: The injection of 0.05 ml of Composition 2 prior to oral surgery for a 3rd molar extraction provides local anesthesia during the surgery and long-lasting local analgesia following the surgery. Similar local analgesia benefits are obtained by locally infiltrating the surgical site with Compositions 1, 3 or 4 immediately following a surgery to provide long-lasting analgesia for surgical site pain.
