Reaction Steps

Part D. To the product from Part C (90 mg, 0.39 mmol), was added 3-(aminocarbonyl)-1-(3-cyano-4-fluorophenyl)-1H-pyrazole-5-carboxylic acid (89 mg, 0.33 mmol), 3.0 mL of pyridine and 1.0 mL of DMF. 1,3-Diisopropylcarbodiimide (0.056 mL, 0.36 mmol) was added, and the resulting solution was stirred for 14 h. The red mixture was 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 preparative LC/MS (C18 reverse phase, eluted with 0.05% TFA in CH3CN/H2O) gave 1-(3-cyano-4-fluorophenyl)-5-{[6-(2-oxohexahydro-1H-azepin-1-yl)-2,3-dihydro-1H-indol-1-yl]carbonyl}-1H-pyrazole-3-carboxamide (67, 29% mg) as a white foam. LC/MS (ESI+): 487.2 (M+H)+.
