Procedure

To a solution of 5-bromo-3-(4-piperidinyl)-1H-indole-7-carboxamide (500 mg, 1.3 mmol) in methylene chloride at room temperature, triethylamine (0.44 mL, 3.2 mmol) and 2-chloroethylsulfonyl chloride (0.168 mL, 1.6 mmol) were added. The reaction mixture was stirred for 30 min. Removed the solvent, the residue was purified by combiflash to give the title compound (150 mg, 75%).
