Procedure

To a solution of 3-[1-(ethylsulfonyl)-4-piperidinyl]-5-(5-formyl-3-thienyl)-1H-indole-7-carboxamide (50 mg, 0.11 mmol) in DMSO (2.0 mL) was added 2 drops of acetic acid, ethyl(methyl)amine (59 mg, 1.0 mmol), and stirred at room temperature for 5 h. To this was then added sodium triacetoxyborohydride (212 mg, 1.0 mmol) and reacted overnight. It was then purified by Gilson Preparatory HPLC to give 30.0 mg of the title compound (61.4%).
