Procedure

To a solution of 3-[1-(ethylsulfonyl)-4-piperidinyl]-5-(4-formylphenyl)-1H-indole-7-carboxamide (40 mg, 0.09 mmol) in DMSO (900 μL) and acetic acid (2 drops) was added 3-pentanamine (108 μL, 1.08 mmol). After 2 h, sodium triacetoxyborohydride (172 mg, 0.81 mmol) was added. Reaction mixture was stirred overnight. Compound was purified by Gilson Preparatory HPLC to afford 34.5 mg of the title compound (74%).
