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-propylpyrrolidine (113 mg, 1.0 mmol). The reaction mixture was then reacted in a microwave at 120° C. for 10 min. Sodium triacetoxyborohydride (220 mg, 1.0 mmol) was then added and the reaction was reacted at room temperature overnight. It was then purified by Gilson Preparatory HPLC to give 21.0 mg of the title compound (38.7%).
