Procedure

To a solution of 5-(5-formyl-3-thienyl)-3-{1-[(1-methylethyl)sulfonyl]-4-piperidinyl}-1H-indole-7-carboxamide (25 mg, 0.054 mmol) in DMSO (2 mL) was added D-prolinamide (114 mg, 1 mmol) and 2 drops of acetic acid. The resulting mixture was stirred at room temperature for 4 h followed by an addition of sodium triacetoxyborohydride (212 mg, 1.0 mmol). The mixture was reacted overnight. It was then purified by Gilson Preparatory HPLC to give 20.4 mg of the title compound.
