Pyrrolidine → 5-[5-(1-pyrrolidinylmethyl)-2-thienyl]-3-(1-{[3-(1-pyrrolidinyl)propyl]sulfonyl}-4-piperidinyl)-1H-indole-7-carboxamide

Participants

Reaction Steps

To a solution of 5-(5-formyl-2-thienyl)-3-(1-{[3-(1-pyrrolidinyl)propyl]sulfonyl}-4-piperidinyl)-1H-indole-7-carboxamide (8.3 mg, 0.016 mmol) in methylene chloride (5 mL) was added pyrrolidine (0.001 mL, 0.016 mmol). The reaction mixture was stirred at room temperature for 1 hour before NaBH(OAc)3 (10.2 mg, 0.048 mmol) was added. The reaction mixture was stirred at room temperature overnight and evaporated all the solvent. The residue was purified by using a Gilson semi-preparative HPLC system, eluting with 10% B to 80% B, where A=H2O (0.1% trifluoroacetic acid) and B=CH3CN (0.1% trifluoroacetic acid) pumped at 25 mL/min to give the title compound (7 mg, 92%).
