Description: TITLE Method for Preparing Alkylating Agents and Their Use for Alkylating Cyclic Ureas FIELD OF THE INVENTION This invention relates to methods for preparing alkylating agents and use of the agents prepared. In particular, this invention relates to preparation methods for hydroxy halide and organooxy halide alkylating agents and their use for alkylating cyclic urea compounds. BACKGROUND OF THE INVENTION Few methods are known for the preparation of hydroxy halide and organooxy halide alkylating agents. Hydroxymethylaryl halides have been prepared from the corresponding aryldimethanols by treatment with hydrogen halides. The reported yields of the desired compounds from aryldimethanols having two equivalent functional groups are generally about 50% or less. For example, Traylor and Ware in J. Amer. Chem. Soc. 89, 2304-2316 (1967) report only a 16% yield of p-hydroxymethylbenzyl chloride from 1,4-benzenedimethanol (p-xylene-ccα 1 -diol) . Yamato et al. in Synthesis, pp. 1014-1015 (December, 1982) report a 53% yield of o-bromomethylbenzyl alcohol from 1,2-benzenedimethanol. A 90% yield of 4-hydroxymethyl-2,3,4,5- tetrafluorobenzyl bromide obtained from 1,4- bis(hydroxymethyl) -2,3,4,5-tetrafluorobenzene by treatment with 48% hydrobromic acid was reported by Costello and Milner in Synthetic Communications , 17 , 219-221 (1987) . However, it has since been shown that treatment of benzenedimethanols lacking nuclear halogen substituents shows no particular selectivity, and accordingly, the unusually high yield in this isolated example is believed to be an anomaly due to insolubility of the monohalogenated product in the reaction media. Lam et al., PCT International Publication Number WO 93/07128 discloses cyclic carbonyl compounds and derivatives thereof which are useful as human immunodeficiency virus (HIV) protease inhibitors for the treatment of HIV infection. The compounds disclosed in WO 93/07128 include cyclic urea compounds of the formula below where W may be -N(R 2 )C(=0)N(R 23 ) -. WO 93/07128 discloses compounds wherein groups R 5 and R 6 may be -O-MEM (MEM = 2-methoxyethoxymethyl), -O-SEM (SEM = 2- (trimethylsilyl)ethoxymethyl) or -O-MOM (MOM = methoxymethyloxy) or may be taken together to form an acetonide ring. WO 93/07128 also discloses processes for the preparation of alkylated cyclic ureas. The processes of the present invention provide improved alkylating agents and processes for the alkylation of the urea nitrogens to obtain such cyclic urea HIV protease inhibitor compounds. As disclosed in WO 93/07128, such cyclic urea compounds, which may be made using the processes of the present invention are non-peptidic, low molecular weight, orally bioavailable compounds useful as inhibitors of HIV protease and for the treatment of HIV infection. The HIV protease inhibitory activity of the cyclic urea can be increased by two to three orders of magnitude by alkylating one or both of the urea nitrogens. Consequently, a need exists for efficient and cost-effective methods for the preparation of the cyclic urea HIV protease inhibitor compounds of WO 93/07128. The present invention provides processes for the preparation of hydroxy halide and organooxy halide alkylating agents in high yields from readily available starting materials. The alkylating agents of the present invention are effective alkylating agents for the alkylation of cyclic urea nitrogens. SUMMARY OF THE INVENTION The present invention includes a process for preparing a hydroxy halide alkylating agent or an organooxy halide alkylating agent of formula (I) : (i) wherein R 3 , m, Q, n, and X are defined below, said method comprising the steps of: (l) reacting an organodiol of formula (II) (ID with a halogenating reagent, to form a compound of formula (IA) : (IA) ; and (2) reacting compound (IA) with a reagent suitable for the protection of hydroxy groups to form the compound of formula (I) where R 3 is a hydroxy protecting group. The present invention also includes a method for alkylating a cyclic urea compound of formula (IV) : (IV) wherein R 4 , R 4A , R 5 , R 5A , q, R 7 ,and R 7A are defined below, comprising steps (1) and (2) above and the additional step of: (3) reacting compound (IV) with compound (I) to form a compound of formula (V) : (V) wherein R 3 is a hydroxy protecting group and R 4 , R 4A , R 5 , R 6 , R 7 , R 7A , m, n and q are as defined below.

The processes of the present invention are useful for the preparation of cyclic HIV protease inhibitors, including cyclic urea HIV protease inhibitors, and for the synthesis of compounds useful as intermediates for the synthesis of such cyclic protease inhibitors. Such cyclic HIV protease inhibitors are useful for the inhibition of HIV and the treatment of HIV infection. Such cyclic HIV protease inhibitors are also useful for the inhibition of HIV in an ex vivo sample containing HIV or expected to be exposed to HIV. Thus, such cyclic HIV protease inhibitors may be used to inhibit HIV present in a body fluid sample (for example, a serum or semen sample) which contains or is suspected to contain or be exposed to HIV. Such cyclic HIV protease inhibitors are also useful as standard or reference compounds for use in tests or assays for determining the ability of an agent to inhibit viral replication and/or HIV protease, for example in a pharmaceutical research program. . Thus, such cyclic HIV protease inhibitors may be used as a control or reference compound in such assays and as a quality control standard. Such cyclic HIV protease inhibitors may be provided in a commercial kit or container for use as such standard or reference compound. Since such cyclic HIV protease inhibitors exhibit specificity for HIV protease, they may also be useful as diagnostic reagents in diagnostic assays for the detection of HIV protease. Thus, inhibition of the protease activity in an assay by such a cyclic HIV protease inhibitor would be indicative of the presence of HIV protease and HIV virus.

Included within this term are modified and unusual amino acids, such as those disclosed in, for example, Roberts and Vellaccio (1983) The Peptides, 5: 342-429, the teaching of which is hereby incorporated by reference. Modified or unusual amino acids which can be used to practice the invention include, but are not limited to, D-amino acids, hydroxylysine, 4-hydroxyproline, an N-Cbz- protected amino acid, omithine, 2,4-diaminobutyric acid, homoarginine, norleucine, N-methylaminobutyric acid, naphthylalanine, phenylglycine, β-phenylproline, tert-leucine, 4-aminocyclohexylalanine, N-methyl- norleucine, 3,4-dehydroproline, N,N- dimethylaminoglycine, N-methylaminoglycine, 4-aminopiperidine-4-carboxylic acid, 6-aminocaproic acid, trans-4- (aminomethyl) -cyclohexanecarboxylic acid, 2-, 3-, and 4- (aminomethyl) -benzoic acid, l-aminocyclopentanecarboxylic acid, 1-aminocyclopropanecarboxylic acid, and 2-benzyl-5- aminopentanoic acid. The term "amino acid residue" as used herein means that portion of an amino acid (as defined herein) that is present in a peptide. The method of the invention comprises the following steps as described further below. Step (l) : Step (1) (the halogenation step) comprises reacting an organodiol compound of the formula (II) with a halogenating reagent. The halo group is preferably chloro, bromo, or iodo. Such halogenating reagents may include, but are not limited to, thionyl halides, such as thionyl chloride and thionyl bromide; oxalyl halides, such as oxalyl chloride and oxalyl bromide; phosphorous pentahalides, such as phosphorous pentachloride and phosphorous pentabromide; phosphorous oxychloride; and iodination reagents. Preferably, the halogenating reagent is thionyl chloride. The halogenation reaction step (1) is conducted in a suitable aprotic solvent, preferably a chlorinated organic solvent. Such chlorinated organic solvents useful in the method of the invention may include, but are not limited to, chloroform, methylene chloride, tetrachloroethane, butyl chloride and dichloroethane. Preferably, the chlorinated organic solvent is selected from chloroform or methylene chloride. The halogenation reaction can be conducted at a temperature of from about -40° C to about the boiling point of the reaction solvent selected, 61° C in the case of chloroform. Preferably, the temperature of the reaction is about 0° C to about room temperature. The time required for completion of the reaction may range from about 1 hour to about 5 days, depending on the combination of halogenating reagent, solvent and regioisomer of compound (II) selected. The reaction can be run under nitrogen or in the presence of slightly humid air, provided that any changes in concentration and integrity of the reagents due to decomposition are compensated for. The product of the reaction step (1) of compound (II) with a halogenating reagent is a hydroxy halide alkylating agent having a formula: (IA) Step (2) . Organooxy halide alkylating agents of formula (I) where R 3 is a hydroxy protecting group are prepared by reacting the compound of formula (IA) with a reagent suitable for the protection of hydroxy groups (also referred to herein as a hydroxy protecting group reagent) to provide an R 3 hydroxy protecting group whose incorporation in formula (IA) will serve to protect the hydroxyl functionality. Such protecting groups include those listed in Greene and Wuts, "Protective Groups in Organic Synthesis", John Wiley & Sons, New York (1991) , the disclosure of which is hereby incorporated by reference. The hydroxy protecting groups are base-stable and can include, but are not limited to acyl types, aromatic carbamate types and alkyl types. Exemplary are methyl, methoxymethyl, methylthiomethyl, benzyloxymethyl, t-butoxymethyl, 2-methoxyethoxymethyl, 2,2,2-trichloroethoxymethyl, 2- (trimethylsilyl)ethoxymethyl, tetrahydropyranyl, tetrahydrofuranyl, t-butyl, triphenylmethyl, trimethylsilyl, triethylsilyl, t-butyldimethylsilyl, t-butyldiphenylsilyl, pivaloate or N-phenylcarbamate. A preferred hydroxy protecting group is triphenylmethyl since it facilitates the isolation of compounds (I) and (V) in high purity, without the use of chromatography. Reaction conditions used for incorporation of the hydroxy protecting groups can also be found in the Greene and Wuts reference cited above. These reaction conditions may be modified to include other combinations of reagents, such as dimethylacetamide as solvent, use of acid scavengers such as Hunig's base (N, N-diisopropylethylamine) , and use of less than one equivalent of hydroxy protecting group reagent to optimize yield of the products. The possible undesired reaction of the hydroxy protecting group reagent containing the R 3 hydroxy protecting group with X under basic conditions may lead to the formation of undesired by-products. Acid catalyzed protection of an alcohol is a reversible reaction and in the case of triphenylmethylation, can lead to aldehyde formation as reported by Smith and Smith, J. Am . Chem. Soc , 70, 2400-2401 (1948). It has been found in the present invention that HCI catalysis gives good yields of the compound of formula (I) where R 3 is triphenylmethyl, when the hydroxy protecting group reagent is triphenylmethyl chloride, triphenylmethyl alcohol, or triphenylmethyl methyl ether. The preferred hydroxy protecting group reagent source for the triphenylmethyl hydroxy protecting group are triphenylmethyl methyl ether or triphenylmethyl alcohol, since azeotropic removal of methanol or water, respectively, drive the triphenylmethylation reaction to completion. The compound of formula (I) may preferably be prepared by carrying out steps (1) and (2) of the present process without the isolation (for example, without isolation by chromatographic separation or precipitation) of the intermediate compound of formula (IA) . Eliminating the need for isolating the intermediate compound of formula (IA) results in an overall increase in the yield of the desired compound of formula (I) in the process of the present invention. Thus, the process of the present invention may be carried out using a "one pot procedure" wherein steps (1) and (2) of the process of the present invention are carried out in one reaction vessel without isolation of compound (IA) between the two steps. A reaction scheme representative of the methods of the invention for preparing hydroxy halide or organooxy halide alkylating agents is shown in the following Scheme 1. „X (II) (IA) 1) Halogenation 2) Protection Protection Z SCHEME 1 (I) Step (3) . The present invention includes a process useful for alkylating cyclic urea compounds of formula (IV) : (IV) which comprises reacting a cyclic urea compound of formula (IV) with a hydroxy-protected compound of formula (I) in the presence of a suitable base. Such suitable bases to provide basic conditions can include, but are not limited to, metal hydrides in non-protic solvents, such as, but not limited to, tetrahydrofuran, ether, N, N-dimethylformamide or 1,3- dimethyl-3,4,5,6-tetrahydro-2 (IH) -pyrimidinone (DMPU) ; a strong metal hydroxide under phase-transfer conditions, such as, but not limited to, water/toluene; or strong metal alkoxides or disilazides in an ethereal solvent, such as, but not limited to, tetrahydrofuran or ether. A preferred base in step (3) is potassium t-butoxide or potassium bis (trimethylsilyl)amide in THF. The method yields reaction products of formula (V) : (V) wherein R 3 is a hydroxy protecting group. Compounds of formula (V) can be reacted with acid to remove the hydroxy protecting group R 3 (i.e., can be acid-deprotected, substituting R 3 with H) to yield compounds useful as inhibitors of HIV protease and for the treatment of HIV infection and disease. Scheme 2 represents the method for alkylating cyclic urea compounds of formula (IV) . •In the present invention it is preferred that: q is 1; R 4 and R 7 are benzyl; R 5 and R 6 are taken together to form -OC(0. 3 ) 2 0- (acetonide blocked diol) . When R 5 and R 6 are taken together to form -OC(CH 3 ) 2 0- the alkylation reaction rate is increased. Also, when R 5 and R 6 are taken together to form -OC(01 3 ) 2 0- , the product from reaction with 4- (triphenylmethoxymethyl)benzyl chloride is crystalline and easily purifiable. The present invention is further described below with reference to the following specific, non-limiting Examples.

TLC visualization was accomplished using UV light, iodine, 5% phosphomolybdic acid in ethanol and/or ninhydrin spray. Melting points were determined using a Thomas Hoover or Electrothermal 9200 melting point apparatus and are uncorrected. NMR spectra were recorded on a 300 MHz General Electric QE-300, Varian 300, or Varian 400 spectrometer. Examples 1 and 2 demonstrate methods for the preparation of compounds of the formula (I) where R 3 is hydrogen. Examples 3-8 demonstrate the preparation methods of formula (I) compounds where R 3 is a hydroxy protecting group. Examples 9 and 10 demonstrate the alkylation of cyclic urea nitrogens by the compounds of formula (I) . Example l p-Hydroxymethylbenzyl chloride 1,4-benzenedimethanol (13.8g, 0.10 mole) was dispersed in chloroform (100 mL) in a 500 mL three- neck round bottom flask equipped with a magnetic stirring bar, an addition funnel, a nitrogen inlet and a gas scrubber. The mixture was cooled to 0°C in an ice bath. Thionyl chloride (I3.lg, 0.11 mole) dissolved in chloroform (10 mL) was added dropwise over ten minutes with rapid stirring to the cooled mixture. As the addition proceeded, the mixture largely cleared. During the addition step, and for one hour thereafter, the reaction flask was swept with nitrogen which was then passed through the scrubber before venting to the atmosphere. The nitrogen was turned off and the scrubber disconnected. The mixture was allowed to come to room temperature and stirring was continued for 20 hours. Sufficient sodium bicarbonate was added to neutralize any residual hydrogen chloride. The mixture was filtered through a coarse glass frit and the solvent removed under reduced pressure at 35°C. A sample of the residue was chromatographed on silica gel (200g) with an ethyl acetate:hexane (2:3) solvent, p-Hydroxymethyl- benzyl chloride was obtained in 75% yield (11.64g) .

TLC analysis of a sample removed after one hour of stirring at room temperature showed little reaction product formed. After 18 hours, TLC analysis indicated that the product was present. The mixture was concentrated as in Example 1 and the residue purified on a silica gel column (700g) using 1:3 ethyl acetate:hexane followed by 1:2 ethyl acetate:hexane. The title compound, m- hydroxymethylbenzyl chloride, was obtained as a colorless oil (19.39g) in 61.6% yield.

The flask was charged with 2- methoxyethoxymethyl chloride (300g, 2.41 moles) and stirred at 20-25°C while N,N-diisopropylethylamine (500mL, 2.86 moles) was slowly added. The reaction became exothermic and caused the dichloromethane solvent to reflux vigorously for 20 minutes. The contents were then stirred for 24 hours at room temperature.

Thionyl chloride (59.5 g, 500 mmol) was added over 2 hours, keeping the temperature below 10°C. The mixture was then allowed to warm to room temperature and stir 4 hours. Approximately half of the methylene chloride (250 mL) was then removed by atmospheric distillation.
