Procedure:
To a solution of 0.16 g (0.31 mmol) 2-(3,5-bis-trifluoromethyl-phenyl)-N-methyl-N-(6-piperazin-1-yl-4-o-tolyl-pyridin-3-yl)-isobutyramide and 38 mg (0.38 mmol) triethylamine in 4 ml dichloromethane were added 38 mg (0.33 mmol) methanesulfonyl chloride at 0° C. After completed addition the reaction mixture was allowed to warm to room temperature. Conversion was monitored by thin layer chromatography. After complete consumption of the starting material the reaction mixture was diluted with water and extracted with three portions of tert-butyl methyl ether. The combined organic layers were dried over sodium sulfate and concentrated in vacuo. Flash column chromatography gave 0.15 g (75%) of the title compound as a white solid.

Procedure:
First, 8.9 mL (8.0 mmol) of a 0.9 M solution of 2,4-difluorophenylmagnesium bromide prepared by the same method as that in Example 3 was cooled to 0° C., and a solution of 0.83 g (4.0 mmol) of (R)-1-chloro-3-pivaloyloxybutan-2-one in 10 mL of toluene was added dropwise thereto over a period of 5 minutes. After the completion of the dropwise addition, stirring was continued for another 1 hour, and 20 mL of a saturated aqueous solution of ammonium chloride was added to stop the reaction. Furthermore, 10 mL of water was added, and extraction was performed with ethyl acetate (30 mL×2). After drying over anhydrous sodium sulfate, concentration was performed under reduced pressure to obtain 1.57 g of a crude product. A quantitative analysis was performed by HPLC. Thereby, the title compound was obtained in a yield of 94% ((2S,3R)/(2R,3R)=93/7 (the diastereomeric ratio was measured by HPLC under the same HPLC measurement conditions as those in Example 19)).

Procedure:
To a solution of Intermediate 176b (0.10 mmol) and morpholine (17.4 mg, 0.200 mmol) in DCM (3 mL) was added sodium triacetoxyborohydride (31.8 mg, 0.15 mmol) and the resulting yellow solution stirred at RT for 1 h. Water (3 mL) was added and the mixture shaken. The aqueous was extracted with DCM (3 mL), then the combined organics passed through a hydrophobic frit and concentrated in vacuo to leave a vivid yellow gum. Flash chromatography (silica 12 g, 3.5-4.5% (2M NH3 in MeOH) in DCM) gave a vivid yellow gum (70 mg). Prep HPLC (Gemini C18, 25-75% MeCN in water, 0.1% HCO2H, 20 min) and concentration of the desired fractions removed the MeCN. The aqueous was extracted with DCM (3×15 mL), then the combined organics passed through a hydrophobic frit and concentrated in vacuo to leave a glassy orange solid (43.7 mg). Prep HPLC (Gemini C18, 25-50% MeCN in water, 20 min) and concentration of the desired fractions removed the MeCN. The aqueous was extracted with DCM (3×5 mL), then the combined organics passed through a hydrophobic fit and concentrated in vacuo to leave the title compound as a white solid (25.4 mg, 35%).

Thereafter, a saturated sodium bicarbonate aqueous solution was added to the reaction solution, followed by extraction with chloroform. The extract was dried over magnesium sulfate and then concentrated under a reduced pressure. The residue was purified by silica gel column chromatography (chloroform-methanol) and by NH silica gel column chromatography (chloroform-methanol), and then reprecipitated from ethyl acetate, so as to obtain 18 mg of the subject compound.

Procedure:
N-Boc-6-aminocaproic acid (7.58 g) prepared by the method described in a Journal of Medicinal Chemistry (J. Med. Chem., 35, p.272 (1993)) and 7.58 g of 3-amino-9-ethylcarbazole were dissolved in 75 mL of dimethylformamide, and the solution was added with 10.4 g WSC hydrochloride and stirred at room temperature for 3.5 hours. The reaction mixture was added with water and extracted with ethyl acetate. The organic layer was washed with 1 N aqueous sodium hydroxide, 10% aqueous citric acid and saturated brine, then dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by silica gel chromatography (eluent: hexane/ethyl acetate=1/1) to obtain 10.3 g of 3-(N-Boc-6-aminocaproyl)amino-9-ethylcarbazole.

Procedure:
A solution of hydantoin (10 g), fused sodium acetate (20 g), and freshly distilled furfural (12 g) in acetic acid (40 ml) was heated under reflux for 11/4 hours. The dark solution was poured into cold water (400 ml) to precipitate the dark green/yellow product, which was washed with water until neutral and then with cold ethanol to give 14 g (80% theoretical yield) of 5-furfurylidenehydantoin m.p. 232°-5° (decomp.) (H. L. Wheeler and C. Hoffman, Amer. Chem. J., 1911, 45, 368, quote m.p. 232°.) The material was used without further purification.

Procedure:
A microwave vial was charged with 2-amino-3-bromopyridine (0.5 g, 2.9 mmol), phenylboronic acid (0.52 g, 4.3 mmol), sodium bicarbonate (0.31 g, 2.9 mmol), dichlorobis(triphenylphosphine)palladium(II) (0.1 g, 0.14 mmol), dioxane (5 mL) and water (1 mL).
