HCID 11978542(R)-4-chloro-8-oxo-9-(2,2,2-trifluoroethyl)-3,6,7,8,9,10-hexahydroazepino[3,4-e]indazol-7-yl 4-(2-oxo-1,2-dihydroquinolin-3-yl)piperidine-1-carboxylateYield 36.1%

Procedure

(R)-4-chloro-7-hydroxy-9-(2,2,2-trifluoroethyl)-6,7,9,10-tetrahydroazepino[3,4-e]indazol-8(3H)-one (60.0 mg, 0.180 mmol) in THF (10.0 mL, 122 mmol) was added sodium hydride (10.79 mg, 0.450 mmol) followed by 4-nitrophenyl 4-(2-oxo-1,2-dihydroquinolin-3-yl)piperidine-1-carboxylate (106 mg, 0.270 mmol). After stirring for 48 h, most of the solvent was removed, diluted with dichloromethane (30 mL) and neutralized with 1.0 M HCl. The organic phase was separated, dried (Na2SO4) and the crude product was purified by flash chromatography using 5% MeOH in dichloromethane to give (R)-4-chloro-8-oxo-9-(2,2,2-trifluoroethyl)-3,6,7,8,9,10-hexahydroazepino[3,4-e]indazol-7-yl 4-(2-oxo-1,2-dihydroquinolin-3-yl)piperidine-1-carboxylate (38.00 mg, 0.065 mmol, 36% yield). MS (ESI) 588 (M+H); Rf=2.73.
