Procedure

Under ice-cooling, 0.64 g of 5,7-dichloro-6-(2,4,6-trifluorophenyl)imidazo[1,2-a]pyrimidine and 0.79 g of 4-methylpiperidine were mixed. The mixture was allowed to stand at room temperature for one hour, and chloroform and aqueous saturated ammonium chloride solution were added to the reaction mixture. The separated organic layer was washed with water, dried over sodium sulfate and concentrated. The residue was washed with t-butyl methyl ether to give 0.62 g of 5-(4-methylpiperidin-1-yl)-6-(2,4,6-trifluorophenyl)-7-chloroimidazo[1,2-a]pyrimidine
