BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to novel compounds capable of modulating, regulating and/or inhibiting tyrosine kinase signal transduction. The present invention is also directed to methods of regulating, modulating or inhibiting tyrosine kinases, whether of the receptor or non-receptor class, for the prevention and/or treatment of disorders related to unregulated tyrosine kinase signal transduction, including cell growth, metabolic, and blood vessel proliferative disorders.
2. Description of the Related Art
Protein tyrosine kinases (PTKs) comprise a large and diverse class of proteins having enzymatic activity. The PTKs play an important role in the control of cell growth and differentiation.
For example, receptor tyrosine kinase mediated signal transduction is initiated by extracellular interaction with a specific growth factor (ligand), followed by receptor dimerization, transient stimulation of the intrinsic protein tyrosine kinase activity and phosphorylation. Binding sites are thereby created for intracellular signal transduction molecules and lead to the formation of complexes with a spectrum of cytoplasmic signaling molecules that facilitate the appropriate cellular response (e.g., cell division, metabolic homeostasis, and responses to the extracellular microenvironment).
With respect to receptor tyrosine kinases, it has been shown also that tyrosine phosphorylation sites function as high-affinity binding sites for SH2 (src homology) domains of signaling molecules. Several intracellular substrate proteins that associate with receptor tyrosine kinases (RTKs) have been identified. They may be divided into two principal groups: (1) substrates which have a catalytic domain; and (2) substrates which lack such domain but serve as adapters and associate with catalytically active molecules. The specificity of the interactions between receptors or proteins and SH2 domains of their substrates is determined by the amino acid residues immediately surrounding the phosphorylated tyrosine residue. Differences in the binding affinities between SH2 domains and the amino acid sequences surrounding the phosphotyrosine residues on particular receptors are consistent with the observed differences in their substrate phosphorylation profiles. These observations suggest that the function of each receptor tyrosine kinase is determined not only by its pattern of expression and ligand availability but also by the array of downstream signal transduction pathways that are activated by a particular receptor. Thus, phosphorylation provides an important regulatory step which determines the selectivity of signaling pathways recruited by specific growth factor receptors, as well as differentiation factor receptors.
Aberrant expression or mutations in the PTKs have been shown to lead to either uncontrolled cell proliferation (e.g. malignant tumor growth) or to defects in key developmental processes. Consequently, the biomedical community has expended significant resources to discover the specific biological role of members of the PTK family, their function in differentiation processes, their involvement in tumorigenesis and in other diseases, the biochemical mechanisms underlying their signal transduction pathways activated upon ligand stimulation and the development of novel drugs.
Tyrosine kinases can be of the receptor-type (having extracellular, transmembrane and intracellular domains) or the non-receptor type (being wholly intracellular).
The RTKs comprise a large family of transmembrane receptors with diverse biological activities. The intrinsic function of RTKs is activated upon ligand binding, which results in phophorylation of the receptor and multiple cellular substrates, and subsequently in a variety of cellular responses.
At present, at least nineteen (19) distinct RTK subfamilies have been identified. One RTK subfamily, designated the HER subfamily, is believed to be comprised of EGFR, HER2, HER3 and HER4. Ligands to the Her subfamily of receptors include epithelial growth factor (EGF), TGF-α, amphiregulin, HB-EGF, betacellulin and heregulin.
A second family of RTKs, designated the insulin subfamily, is comprised of the INS-R, the IGF-1R and the IR-R. A third family, the “PDGF” subfamily includes the PDGF α and β receptors, CSFIR, c-kit and FLK-II. Another subfamily of RTKs, identified as the FLK family, is believed to be comprised of the Kinase insert Domain-Receptor fetal liver kinase-1 (KDR/FLK-1), the fetal liver kinase 4 (FLK-4) and the fms-like tyrosine kinase 1 (flt-1). Each of these receptors was initially believed to be receptors for hematopoietic growth factors. Two other subfamilies of RTKs have been designated as the FGF receptor family (FGFR1, FGFR2, FGFR3 and FGFR4) and the Met subfamily (c-met and Ron).
Because of the similarities between the PDGF and FLK subfamilies, the two subfamilies are often considered together. The known RTK subfamilies are identified in Plowman et al, 1994, DN&P 7(6): 334–339, which is incorporated herein by reference.
The non-receptor tyrosine kinases represent a collection of cellular enzymes which lack extracellular and transmembrane sequences. At present, over twenty-four individual non-receptor tyrosine kinases, comprising eleven (11) subfamilies (Src, Frk, Btk, Csk, Abl, Zap70, Fes/Fps, Fak, Jak, Ack and LIMK) have been identified. At present, the Src subfamily of non-receptor tyrosine kinases is comprised of the largest number of PTKs and include Src, Yes, Fyn, Lyn, Lck, Blk, Hck, Fgr and Yrk. The Src subfamily of enzymes has been linked to oncogenesis. A more detailed discussion of non-receptor tyrosine kinases is provided in Bolen, 1993, Oncogen 8: 2025–2031, which is incorporated herein by reference.
Many of the tyrosine kinases, whether an RTK or non-receptor tyrosine kinase, have been found to be involved in cellular signaling pathways leading to cellular signal cascades leading to pathogenic conditions, including cancer, psoriasis and hyper immune response.
In view of the surmised importance of PTKs to the control, regulation and modulation of cell proliferation the diseases and disorders associated with abnormal cell proliferation, many attempts have been made to identify receptor and non-receptor tyrosine kinase “inhibitors” using a variety of approaches, including the use of mutant ligands (U.S. Pat. No. 4,966,849), soluble receptors and antibodies (PCT Application No. WO 94/10202; Kendall & Thomas, 1994, Proc. Nat'l Acad. Sci 90: 10705–09; Kim, et al, 1993, Nature 362: 841–844), RNA ligands (Jellinek, et al, Biochemistry 33: 10450–56); Takano, et al, 1993, Mol. Bio. Cell 4:358A; Kinsella, et al, 1992, Exp. Cell Res. 199: 56–62; Wright, et al, 1992, J. Cellular Phys. 152: 448–57) and tyrosine kinase inhibitors (PCT Application Nos. WO 94/03427; WO 92/21660; WO 91/15495; WO 94/14808; U.S. Pat. No. 5,330,992; Mariani, et al, 1994, Proc. Am. Assoc. Cancer Res. 35:2268).
More recently, attempts have been made to identify small molecules which act as tyrosine kinase inhibitors. For example, bis monocyclic, bicyclic or heterocyclic aryl compounds (PCT Application No. WO 92/20642), vinylene-azaindole derivatives (PCT Application No. WO 94/14808) and 1-cyclopropyl-4-pyridyl-quinolones (U.S. Pat. No. 5,330,992) have been described generally as tyrosine kinase inhibitors. Styryl compounds (U.S. Pat. No. 5,217,999), styryl-substituted pyridyl compounds (U.S. Pat. No. 5,302,606), certain quinazoline derivatives (EP Application No. 0 566 266 A1), seleoindoles and selenides (PCT Application No. WO 94/03427), tricyclic polyhydroxylic compounds (PCT Application No. WO 92/21660) and benzylphosphonic acid compounds (PCT Application No. WO 91/15495) have been described as compounds for use as tyrosine kinase inhibitors for use in the treatment of cancer.
The identification of effective small compounds which specifically inhibit signal transduction by modulating the activity of receptor and non-receptor tyrosine kinases to regulate and modulate abnormal or inappropriate cell proliferation is therefore desirable and one object of this invention.
Finally, certain small compounds are disclosed in U.S. Pat. Nos. 5,792,783; 5,834,504; 5,883,113; 5,883,116 and 5,886,020 as useful for the treatment of diseases related to unregulated TKS transduction. These patents are hereby incorporated by reference in its entirety for the purpose of disclosing starting materials and methods for the preparation thereof, screens and assays to determine a claimed compound's ability to modulate, regulate and/or inhibit cell proliferation, indications which are treatable with said compounds, formulations and routes of administration, effective dosages, etc.

The present invention relates to compounds capable of regulating and/or modulating tyrosine kinase signal transduction and more particularly receptor and non-receptor tyrosine kinase signal transduction.
Receptor tyrosine kinase mediated signal transduction is initiated by extracellular interaction with a specific growth factor (ligand), followed by receptor dimerization, transient stimulation of the intrinsic protein tyrosine kinase activity and phosphorylation. Binding sites are thereby created for intracellular signal transduction molecules and lead to the formation of complexes with a spectrum of cytoplasmic signaling molecules that facilitate the appropriate cellular response (e.g., cell division, metabolic effects and responses to the extracellular microenvironment).
It has been shown that tyrosine phosphorylation sites in growth factor receptors function as high-affinity binding sites for SH2 (src homology) domains of signaling molecules. Several intracellular substrate proteins that associate with receptor tyrosine kinases have been identified. They may be divided into two principal groups: (1) substrates which have a catalytic domain; and (2) substrates which lack such domain but serve as adapters and associate with catalytically active molecules. The specificity of the interactions between receptors and SH2 domains of their substrates is determined by the amino acid residues immediately surrounding the phosphorylated tyrosine residue. Differences in the binding affinities between SH2 domains and the amino acid sequences surrounding the phosphotyrosine residues on particular receptors are consistent with the observed differences in their substrate phosphorylation profiles. These observations suggest that the function of each receptor tyrosine kinase is determined not only by its pattern of expression and ligand availability but also by the array of downstream signal transduction pathways that are activated by a particular receptor. Thus, phosphorylation provides an important regulatory step which determines the selectivity of signaling pathways recruited by specific growth factor receptors, as well as differentiation factor receptors.
Tyrosine kinase signal transduction results in, among other responses, cell proliferation, differentiation and metabolism. Abnormal cell proliferation may result in a wide array of disorders and diseases, including the development of neoplasia such as carcinoma, sarcoma, leukemia, glioblastoma, hemangioma, psoriasis, arteriosclerosis, arthritis and diabetic retinopathy (or other disorders related to uncontrolled angiogenesis and/or vasculogenesis, e.g. macular degeneration).
This invention is therefore directed to compounds which regulate, modulate and/or inhibit tyrosine kinase signal transduction by affecting the enzymatic activity of the RTKs and/or the non-receptor tyrosine kinases and interfering with the signal transduced by such proteins. More particularly, the present invention is directed to compounds which regulate, modulate and/or inhibit the RTK and/or non-receptor tyrosine kinase mediated signal transduction pathways as a therapeutic approach to cure many kinds of solid tumors, including but not limited to carcinoma, sarcoma, leukemia, erythroblastoma, glioblastoma, meningioma, astrocytoma, melanoma and myoblastoma. Indications may include, but are not limited to brain cancers, bladder cancers, ovarian cancers, gastric cancers, pancreas cancers, colon cancers, blood cancers, lung cancers and bone cancers.
Biological data for the compounds of the present invention was generated by use of the following assays.
VEGF Stimulated Ca++ Signal in Vitro
Automated FLIPR (Fluorometric Imaging Plate Reader) technology was used to screen for inhibitors of VEGF induced increases in intracellular calcium levels in fluorescent dye loaded endothelial cells. HUVEC (human umbilical vein endothelial cells) (Clonetics) were seeded in 96-well fibronectin coated black-walled plates overnight at 37° C./5% CO2. Cells were loaded with calcium indicator Fluo-4 for 45 minutes at 37° C. Cells were washed 4 times (Original Cell Wash, Labsystems) to remove extracellular dye. Test compounds were reconstituted in 100% DMSO and added to the cells to give a final DMSO concentration of 0.1%. For screening, cells were pre-incubated with test agents for 30 minutes, at a single concentration (10 μM) or at concentrations ranging from 0.01 to 10.0 μM followed by VEGF stimulation (5 ng/1 mL). Changes in fluorescence at 516 nm were measured simultaneously in all 96 wells using a cooled CCD camera. Data were generated by determining max-min fluorescence levels for unstimulated, stimulated, and drug treated samples. IC50 values for test compounds were calculated from % inhibition of VEGF stimulated responses in the absence of inhibitor.
Protocol for KDR Assay:
KDR Assay:
The cytoplasmic domain of the human VEGF receptor (VEGFR-2) was expressed as a Histidine-tagged fusion protein following infection of insect cells using an engineered baculovirus. His-VEGFR-2 was purified to homogeneity, as determined by SDS-PAGE, using nickel resin chromatography. Kinase assays were performed in 96 well microtiter plates that were coated overnight with 30 μg of poly-Glu-Tyr (4:1) in 10 mM Phosphate Buffered Saline (PBS), pH 7.2–7.4. The plates were incubated with 1% BSA and then washed four times with PBS prior to starting the reaction. Reactions were carried out in 120 μL reaction volumes containing 3.6 μM ATP in kinase buffer (50 mM Hepes buffer pH 7.4, 20 mM MgCl2, 0.1 mM MnCl2 and 0.2 mM Na3VO4). Test compounds were reconstituted in 100% DMSO and added to the reaction to give a final DMSO concentration of 5%. Reactions were initiated by the addition 0.5 ng of purified protein. Following a ten minute incubation at 25° C., the reactions were washed four times with PBS containing 0.05% Tween-20. 100 μl of a monoclonal anti-phosphotyrosine antibody-peroxidase conjugate was diluted 1:10000 in PBS-Tween-20 and added to the wells for 30 minutes. Following four washes with PBS-Tween-20, 100%1 of O-phenylenediamine Dihydrochloride in Phosphate-citrate buffer, containing urea hydrogen peroxide, was added to the wells for 7 minutes as a colorimetric substrate for the peroxidase. The reaction was terminated by the addition of 100%1 of 2.5N H2SO4 to each well and read using a microplate ELISA reader set at 492 nm. IC50 values for compound inhibition were calculated directly from graphs of optical density (arbitrary units) versus compound concentration following subtraction of blank values.
VEGF-Induced Dermal Extravasation in Guinea Pig (Miles Assay). Male Hartley guinea pigs (300–600 g) were anesthetized with isofluorane, sheared, and given a single dose of drug or the respective vehicle. The guinea pigs were dosed orally unless indicated otherwise in Table 3. Ten minutes prior to the end of drug treatment, guinea pigs were anesthetized with isofluorane, and 0.5% Evans blue dye (EBD) in PBS (13–15 mg/kg dose of EBD) was injected intravenously. After 5 minutes, triplicate intradermal injections of 100 ng rh VEGF165 in 100 μl PBS and of 100 μl PBS alone were administered on the flank. After 20 minutes, each animal was euthanized with Pentosol, and the skin containing the intradermal injection sites was removed for image analysis.
Using an analog video camera coupled to a PC, an image of each trans-illuminated skin sample was captured, and the integrated optical density of each injection site was measured using ImagePro 4. For each skin sample, the difference between the mean optical density of the VEGF sites and mean optical density of the PBS sites is the measure of VEGF-induced EBD extravasation in that animal. These measured values were averaged per study group to determine the mean VEGF-induced EBD extravasation for each experimental condition, and the group means were then compared to assess inhibition of VEGF-induced EBD extravasation in the drug-treated groups relative to the vehicle-treated controls.
To determine the dose required for 50% inhibition (ID50), the percent inhibition data was plotted as a function of oral dose, using the ‘best-fit’ analysis within MicroSoft Excel software. The ID50 value was verified visually by using the plotted data (horizontal line from 50% y value, at intersection with best-fit line drop vertical line to x axis (dose)).
Laser-Induced Choroidal Neovascularization (CNV) in Rat (CNV Assay).
CNV was induced and quantified in this model as previously described (Edelman and Castro. Exp. Eye Res. 2000; 71:523–533). On day 0, male Brown Norway rats (200–300 g) were anesthetized with 100 mg/kg Ketamine and 10 mg/kg Xylazine, and pupils were dilated with 1% Tropicamide. Using the blue-green setting of a Coherent Novus Argon Laser, 3 laser burns (90 mW for 0.1 s; 100 μm diameter) were given to each eye between the retinal vessels around the optic nerve head. Rats were dosed with test compounds in their indicated vehicles orally once daily.
On day 10, rats were sacrificed with 100% CO2, and blood vessels were labeled by vascular perfusion with 10 mg/ml FITC-dextran (MW 2×106). Using an epifluorescence microscope (20×) coupled to a spot digital camera and a PC, images were obtained from the flat mounts of the RPE-choroid-sclera from each eye, and the area occupied by hyperfluorescent neovessels within each laser lesion was measured using ImagePro 4 software.
To determine the dose required for 50% inhibition (ID50), the percent inhibition data was plotted as a function of oral dose, using the ‘best-fit’ analysis within MicroSoft Excel software. The ID50 value was verified visually by using the plotted data (horizontal line from 50% y value, at intersection with best-fit line drop vertical line to x axis (dose)).
The results of said assays are set forth in Tables 2, 3 and 4 below, wherein NT means not tested.

3-{[4-(2-Morpholin-4-yl-ethylamino)-phenylamino]-methylene}-1,3-dihydro-indol-2-one.
The named compound is prepared by refluxing 1.26 gms. E & Z 3-[(hydroxy)-methylene]-1,3-dihydro-indol-2-one, as prepared in Example 1, with 3.45 gms. of N-(2-morpholin-4-yl-ethyl)-benzene-1,4-diamine in tetrahydrofuran (34.02 mL) for 12 hours. Following concentration in vacuo, dilution with hot isopropanol and filtration provides the named compound is isolated as a yellow solid in the amount of 1.731 gms.
N-(2-Morpholin-4-yl-ethyl)-benzene-1,4-diamine is prepared from p-fluoronitrobenzene by the following method:
A mixture of 7.5 mL of p-fluoronitrobenzene, 10.25 mL 2-morpholin-4-yl-ethylamine and 15 mL N,N-diisopropylamine in 36 mL dioxane is heated at 105° C. for 2 days. The reaction mixture is cooled to room temperature, diluted with dichloromethane (360 mL) and washed with water (3×290 mL). Upon evaporation to dryness, the dichloromethane layer yields the (2-morpholin-4-yl-ethyl)-(4-nitro-phenyl)-amine product, which is recrystallized from methanol.
A suspension of 4.05 gms. of (2-morpholin-4-yl-ethyl)-(4-nitro-phenyl)-amine in 93 mL of ethanol is heated to 50° C. Once dissolution is achieved 4.8 mL hydrazine monohydrate is added to the solution. A Raney nickel 2800 slurry in water (approximately 3.5 mL) is added to the 50° C. solution dropwise, waiting after each addition for the bubbling to cease. Sufficient quantities of Raney nickel have been added when continued addition of Raney nickel causes no further gas evolution. The reaction is then maintained at 50° C. for an additional hour, and subsequently is cooled to room temperature. The reaction mixture is filtered through a pad of celite (rinsing the pad with methanol). The N-(2-morpholin-4-yl-ethyl)-benzene-1,4-diamine (3.45 gms.) is isolated upon evaporation of the filtrate, and is subsequently used without purification in the reaction of Example 235.
Examples 242, 243, 244, and 245 are prepared by substituting the appropriate 4′-methyl or 6′-fluoro or 5′-fluoro or 5′-chloro substituted 1,3-dihydro-indol-2-one for the 1,3-dihydro-indol-2-one and N-(2-morpholin-4-yl-ethyl)-benzene-1,4-diamine, used for the preparation of Example 235, for aniline in the reaction of Example 1.

Following cooling to room temperture, solvent evaporation in vacuo, trituration with isopropanol and filtration the reaction yields the named compound as a solid in the amount of 0.038 gms.
Piperidin-1-ylmethyl-phenylamine is prepared from 4-nitro-benzoic acid by the following method:
A room temperature solution of 5.04 gms. 4-nitro-benzoic acid in tetrahydrofuran (10 mL) is treated with 5.14 gms. 1′,1′-carbonyl-diimidizole and immediately immersed in an ice bath. The reaction mixture is stirred in the ice bath for 30 minutes, then it is allowed to warm to room temperature. Once at room temperature the reaction mixture is treated with 3 mL piperidine. The reaction mixture is allowed to stir at room temperature ovenight. The reaction is then made basic with the addition of saturated aqueous sodium bicarbonate solution, and the resulting mixture is extracted with ethyl acetate. The organics are separated, dried over anhydrous sodium sulfate, and subsequently evaporated to dryness in vacuo. The crude product residue is then chromatographed by flash silica gel chromatography using 50% ethyl acetate in hexanes as the eluant. Following evaporation of solvent, 1-(4-nitrobenzoyl)piperidine is isolated as a white solid in the amount of 5.87 gms.
1-(4-Nitrobenzoyl)piperidine (0.1125 gms.) is then dissolved in tetrahydrofuran (1 mL) and slowly added dropwise to a 0° C., 1.0 M solution (4 mL) of Borane in tetrahydrofuran. The reaction mixture is maintained at 0° C. for 20 minutes following the completion of the addition to the Borane/tetrahydrofuran solution. The reaction mixture is then allowed to warm to room temperature, and is subsequently heated to 60° C. using an oil bath. The reaction mixture is maintained at 60° C. overnight, then is cooled to room temperature, and quenched with the addition of concentrated HCl (added until gas evolution stops). The quenched reaction mixture is then extracted with ethyl acetate and water. The organic layer is separated, and concentrated in vacuo, while the aqueous layer is separated and made basic with the addition of aqueous 1M NaOH. The basic aqueous layer is then extracted with ethyl acetate and the ethyl acetate layer from this extraction is concentrated in vacuo. The solids isolated from both concentrated ethyl acetate layers are combined to yield 92 mg of 1-(4-nitro-benzyl)-piperidine as a white-yellow solid.
1-(4-Nitro-benzyl)-piperidine (0.5052 gms.) is suspended in 25 mL of a 1:1 (v:v) solution of acetic acid and water. The suspension is then treated with 45 mL of an  ̃10 wt. % solution of TiCl3 in 20–30 wt. % HCl, dropwise. Over the course of the addition a color change from colorless to purple to black ensues. The reaction mixture is immersed in a 60° C. oil bath overnight following the addition of TiCi3. The reaction mixture is then cooled to room temperature and made basic with the addition of a 10% aqueous solution of NaOH. The basic reaction mixture is extracted with chloroform, and the organic layer is dried over anhydrous sodium sulfate. Following evaporation of the solvent the organic layer yields 0.333 gms. of piperidin-1-ylmethyl-phenylamine.

Following cooling to room temperature, solvent evaporation in vacuo, trituration with isopropanol (plus a little chloroform) and filtration the reaction yields the named compound as a solid in the amount of 16.2 mg.
E & Z 3-Hydroxymethylene-6-(3-methoxy-phenyl)-1,3-dihydro-indol-2-one is prepared in 5 steps from 4-Bromo-1-fluoro-2-nitro-benzene by the following method:
4-Bromo-1-fluoro-2-nitro-benzene (5 gms.), 3.85 gms. 3-methoxyphenylboronic acid and 22 mL of a 2M aqueous solution of sodium carbonate are suspended in 100 mL of a 1:1 (v:v) mix of toluene and ethanol. The resulting suspension is then treated with 0.8 gms. tetrakis(triphenylphosphine)palladium (0) at room temperature. The reaction mixture is then heated at reflux for 12 h. The reaction mixture is subsequently concentrated in vacuo, and the resulting residue is taken up in ethyl acetate (200 mL). The ethyl acetate solution is then washed successively with water (2×200 mL), and brine (2×200 mL). The organic layer is then dried by filtering through phase separator paper and concentrated in vacuo to yield 7.19 gms. of crude product. The crude product is then recrystallized from hot ethanol yielding 4-fluoro-3′-methoxy-3-nitro-biphenyl as a yellow-white solid in the amount of 4.767 gms.
A room temperature DMSO (50 mL) suspension of a 60% dispersion of sodium hydride in mineral oil (3.94 gms.) is treated dropwise with 10.41 mL of dimethylmalonate. The suspension is then heated to 100° C. for 35 minutes and subsequently treated with a solution of 4-fluoro-3′-methoxy-3-nitro-biphenyl (4.6138 gms.) in DMSO (55 mL). The reaction mixture is heated at 100° C. for an additional 1 h after which it is cooled to room temperature, and quenched with the addition of a saturated aqueous solution of ammonium chloride (300 mL). The quenched reaction mixture is then extracted with ethyl acetate (3×300 mL). The combined ethyl acetate washes are then washed with brine (1×500 mL), filtered through phase separator paper to dry the solution, and then concentrated in vacuo. The crude residue isolated is recrystallized from isopropanol/ethyl acetate yielding 2-(3′-methoxy-3-nitro-biphenyl-4-yl)-malonic acid dimethyl ester in the amount of 4.4023 gms.
2-(3′-Methoxy-3-nitro-biphenyl-4-yl)-malonic acid dimethyl ester (4.4023 gms.) is suspended in 45 mL of 6N HCl and heated at 110° C. for 4 days. The reaction mixture is cooled to room temperature and the precipitate is collected by filtration. As the solid material is in rather large chunks, the solid purification is simplified by first dissolving the solid chunks in an excess of hot methanol, and subsequently concentrating the solution in vacuo to get a more manageable powder. This powder is then triturated with approximately 10 mL of methanol and filtered yielding (3′-methoxy-3-nitro-biphenyl-4-yl)-acetic acid in the amount of 2.0120 gms.
A solution of (3′-Methoxy-3-nitro-biphenyl-4-yl)-acetic acid (2.0120 gms.) in 35 mL methanol is treated with 0.3123 gms. of 10% palladium on carbon. The resulting suspension is then stirred vigorously under an atmosphere of hydrogen at room temperature and atmospheric pressure for 3 h. The reaction mixture is then filtered through a pad of celite, the filtrate is treated with decolorizing charcoal and filtered a second time through celite. The filtrate is then concentrated in vacuo and purified by trituration with isopropanol yielding 0.5736 gms. of 6-(3-methoxy-phenyl)-1,3-dihydro-indol-2-one.
6-(3-Methoxy-phenyl)-1,3-dihydro-indol-2-one (0.2282 gms.) is combined with 0.23 mL of ethylformate in 0.67 mL anhydrous ethanol, and is treated with a solution of 21%, by weight, sodium formate in ethanol (0.40 mL). The resulting solution is allowed to stand at room temperature for 30 minutes, and then is refluxed for 2 h to yield a suspension. Once at room temperature the suspension is acidified to pH 1.0 with 10% HCl (aq), then diluted with 5 mL of H2O. The resulting precipitate was filtered and washed with H2O (4×20 mL) to provide a mixture of E & Z 3-hydroxymethylene-6-(3-methoxy-phenyl)-1,3-dihydro-indol-2-one, as a solid in the amount of 0.2064 gms.

The reaction mixture is stirred for 30 minutes in the ice bath and 30 minutes at room temperature. The reaction mixture is then treated with 0.5 mL morpholine. The reaction was heated overnight at 35° C. The reaction is then allowed to cool to room temperature, and is made basic with the addition of saturated aqueous sodium bicarbonate. The resulting mixture is extracted with ethyl acetate. The organics are dried over anhydrous sodium sulfate, filtered and evaporated to dryness in vacuo. The crude product residue is then purified by filtering it through a plug of silica gel using 50% ethyl acetate in hexanes as the eluant. Following evaporation of solvent, 4-(4-nitro-phenyl)-1-piperidin-1-yl-butan-1-one is isolated as a yellow oil in the amount of 1.47 gms.
4-(4-Nitro-phenyl)-1-piperidin-1-yl-butan-1-one (1.465 gms.) is then dissolved in tetrahydrofuran (7.0 mL) and added dropwise to a 0° C., 1.5M solution (25 mL) of Borane in tetrahydrofuran. The reaction mixture is maintained at 0° C. for 30 minutes following the completion of the addition to the Borane/tetrahydrofuran solution. The reaction mixture is then allowed to warm to room temperature for an hour, and is subsequently refluxed using an oil bath. The reaction mixture is maintained at refluxing temperature overnight, then cooled to 0° C. and quenched with the addition of concentrated HCl (added until gas evolution stops). The quenched reaction mixture is then warmed to room temperature, and extracted with ethyl acetate and water. The emulsion that forms is filtered through glass wool and the layers are separated. The aqueous layer is then extracted three additional times with ethyl acetate. The combined organic layers are concentrated in vacuo. The solid isolated is then chromatographed by flash silica gel chromatography using 30% ethyl acetate in hexanes as the eluant yielding 0.719 gms. of 1-[4-(4-nitro-phenyl)-butyl]-piperidine.
1-[4-(4-Nitro-phenyl)-butyl]-piperidine (0.719 gms.) is suspended in 30 mL of a 1:1 (v:v) solution of acetic acid and water. The suspension is then immersed in a 60° C. oil bath and treated in dropwise fashion with 40 mL of an 10 wt. % solution of TiCl3 in 20–30 wt. % HCl. The reaction mixture is maintained in the 60° C. oil bath overnight following the addition of TiCl3. The reaction mixture is then cooled to 0° C., and is made basic with the addition of a 10% aqueous solution of NaOH. The basic reaction mixture is then extracted with chloroform. The emulsion that forms is filtered through glass wool, and then the layers are separated. The aqueous layer is re-extracted with ethyl acetate three additional times. The combined organic layers are concentrated in vacuo and the residue is chromatographed by flash silica gel chromatography (10% methanol in chloroform) yielding 0.428 gms. of 4-(4-piperidin-1-yl-butyl)-phenylamine.

The named compound is prepared by refluxing 0.0410 gms. E & Z-3-Hydroxymethylene-4-methyl-1,3-dihydro-indol-2-one, as prepared in the reaction of Example 1, with 0.070 gms. 4-(4-piperidin-1-yl-butyl)-phenylamine (used in the preparation of Example 318) in tetrahydrofuran (1.0 mL) overnight. Following cooling to room temperture, solvent evaporation in vacuo, trituration with isopropanol and filtration the reaction yields the named compound as a solid in the amount of 38.3 mg.
Examples 319 and 321–323 are prepared by substituting the appropriate 5′-chloro or 4′-fluoro or 5′-fluoro or 6′-fluoro substituted 1,3-dihydro-indol-2-one for the 1,3-dihydro-indol-2-one and 4-(4-piperidin-1-yl-butyl)-phenylamine, used in the preparation of Example 318, for aniline in the reaction of Example 1.
