Procedure

Part B. To the product from Part A (95 mg, 0.41 mmol), was added 3-(aminocarbonyl)-1-(3-cyano-4-fluorophenyl)-1H-pyrazole-5-carboxylic acid (94 mg, 0.34 mmol), 3.3 mL of pyridine, and 0.70 mL of DMF. 1,3-Diisopropylcarbodiimide (0.059 mL, 0.38 mmol) was added, and the resulting solution was stirred for 1 h. The red mixture was then poured into 1N aqueous HCl (70 mL) and washed with EtOAc (3×50 mL). The combined organic layers were washed with brine, dried over Na2SO4, and filtered. Concentration of the filtrate and purification of the resulting residue by radial chromatography (1-5% MeOH in CH2Cl2) gave 1-(3-cyano-4-fluorophenyl)-5-{[5-(2-oxohexahydro-1H-azepin-1-yl)-2,3-dihydro-1H-indol-1-yl]carbonyl}-1H-pyrazole-3-carboxamide (98 mg, 49%) as a brown residue. LC/MS (ESI+): 487.1 (M+H)+. 1H NMR (CD3OD) δ 8.08 (br m, 1H), 7.97 (br d, 1H), 7.87 (br s, 1H), 7.43 (br t, 1H), 7.28 (s, 1H), 7.12 (br s, 1H), 7.00 (br d, 1H), 4.24 (br m, 2H), 3.73 (br s, 2H), 3.16 (br m, 2H), 2.66 (br s, 2H), 1.79 (br s, 6H).
