Procedure

To solution of (7R)-4-chloro-10-[1-(trifluoromethyl)cyclopropyl]-3,6,7,12-tetrahydroimidazo[1′,2′:1,7]azepino[3,4-e]indazol-7-amine (100 mg, 0.3 mmol) and triethyl amine (120 uL, 0.9 mmole) is added 4-nitrophenyl chloroformate (60 mg, 0.3 mmol) and stirred at 0° C. for 1 hr. 1-Piperidin-4-yl-1,3-dihydro-2H-imidazo[4,5-b]pyridin-2-one dihydrochloride [Burgey et al. WO 2006/044504], (87 mg, 0.3 mmol), is added along with triethylamine (120 uL, 0.9 mmol) and the reaction mixture is stirred at ambient temperature for 18 h. Saturated aqueous sodium carbonate (50 mL) is added and the mixture is extracted with dichloromethane (3×25 mL) The combined organic layers are washed with saturated aqueous sodium bicarbonate, brine, dried over sodium sulfate, filtered and concentrated. Purification by silica gel chromatography [100% dichloromethane→93% dichloromethane/methanol] provides the title compound.
