The mixture was stirred for 1 hour at room temperature and was evaporated to dryness. The residue was purified by flash chromatography on silica gel (eluent 2 to 20% ethyl acetate in dichloromethane) to furnish 2.60 g (88%) of N-(2-(5-chloro-1H-indol-3-yl)ethyl)-4-(chloromethyl)benzamide as a white solid.
