실험 절차

A mixture of 1.0 g (3.7 mmol) of 2-(2,4-dichlorophenyl)-5,6,7,8-tetrahydroimidazo[1,2-a]pyridine and 0.6 g (4.5 mmol) of N-chlorosuccinimide was stirred in 15 ml of dimethylformamide at room temperature overnight followed by heating at 70° C. for 20 minutes. An excess of water was added and the aqueous mixture extracted with 200 ml of ethyl acetate. The separated organic layer layer was washed with water, saturated aqueous sodium bicarbonate, and brine. After drying over magnesium sulfate, the solvent was removed in vacuo to give a oily residue. Silica gel column chromatography (3:1 followed by 1:1 hexane/ethyl acetate followed in turn by 2:1 ethyl acetate/hexane) afforded the title compound as the main component (0.65 g, m.p. 99°-101° C.).
