反応手順

A suspension of 1H-pyrrolo[2,3-c]pyridine (0.95 g, 8.05 mmol), tert-butyl (4-oxocyclohexyl)carbamate (1.82 g, 8.54 mmol) and KOH (0.95 g, 17.0 mmol) in MeOH (10 mL) was heated at reflux overnight. The solution was added to ice-water (50 mL) and then MeOH (50 mL) was added. The resulting solution was concentrated to circa 50 mL and extracted three times with DCM/MeOH (9:1, 50 mL) and the organic layers were combined and concentrated. The residue was purified by flash chromatography (9:1 DCM/MeOH) to give the title compound as a white solid (1.96 g, 78%). MS (ESI+) m/z=314 (M+H)+.
