Procedure

To a solution of 3-[1-(ethylsulfonyl)-4-piperidinyl]-5-(3-formylphenyl)-1H-indole-7-carboxamide (20 mg, 0.046 mmol) in dichloromethane (0.7 mL) and methanol (0.7 mL) was added propylamine (22 uL, 0.27 mmol) and 1 drop of acetic acid. This mixture was stirred for 1 h at room temperature and then sodium borohydride (10 mg, 0.27 mmol) was added. The reaction was stirred overnight at ambient temperature, and the solvent was removed under reduced pressure. The crude product was purified by reverse phase HPLC (water/CH3CN, 0.1% TFA 10-90%) to give the title compound (22.1 mg, 99%).
