Procedure

To a solution of tetrahydro-3-furancarboxylic acid (17 mg, 0.144 mmol) in DCM (2.0 mL) was added pyridine (3 drops) and oxalyl chloride (18 mg, 0.144 mmol). Reaction mixture was stirred overnight at room temperature. To the mixture was then added 5-[3-(aminomethyl)phenyl]-3-[1-(ethylsulfonyl)-4-piperidinyl]-1H-indole-7-carboxamide (40 mg, 0.096 mmol) in DMF (1.0 mL) and DIEA (33 μL, 0.192 mmol). Reaction mixture was stirred at room temperature overnight. Reaction mixture was concentrated under nitrogen and purified by Gilson Preparatory HPLC to give 5.3 mg the title compound (10%).
