Participants

Reaction Steps

To a solution of 3-[1-(ethylsulfonyl)-4-piperidinyl]-5-(2-fluoro-5-formylphenyl)-1H-indole-7-carboxamide (20 mg, 0.04 mmol) in dichloromethane (4 mL) and methanol (2 mL) was added 2 drops of acetic acid and 2,2,2-trifluoroethanamine (23 μL, 0.26 mmol). The resulting mixture was stirred overnight. All solvent was evaporated and dissolved in dimethyl sulfoxide (1 mL). Purified by Gilson Preparatory HPLC to give 5.2 mg of the title compound (24.0%).
