Procedure

To a solution of 3-[1-(ethylsulfonyl)-4-piperidinyl]-5-[4-(2-oxoethyl)phenyl]-1H-indole-7-carboxamide (50 mg, 0.11 mmol) in methanol (5 mL) and methylene chloride (5 mL) at room temperature was added 2 M ethylamine in tetrahydrofuran (0.4 mL), followed by 1 drop of acetic acid. The reaction was stirred at room temperature for 2 h followed by an addition of sodium triacetoxyborohydride (200 mg, 0.94 mmol). This reaction was stirred overnight. It was then purified by flash chromatography to give 15 mg of the title compound (28.3%).
