反応手順

To a solution of 3-chloro-N-[1-(2-chlorophenyl)-2-(piperidin-4-ylmethoxy)ethyl]-1H-indole-6-carboxamide (600 mg, 1.3 mmol) in 5 mL of methanol was added triethylamine (0.37 mL, 2.7 mmol) and trifluoroacetic acid ethyl ester (0.20 mL, 2.7 mmol). The reaction was allowed to stir at room temperature overnight after which time water was added and the resulting precipitate was isolated by filtration. Purification of the filtrate (SiO2: 10:2:0.5 DCM:hexane:isopropylamine) provided 297 mg (41%) of the title compound.
