Reaction Steps

A mixture of 2,2,2-trichloroethyl [6-(acetylamino)pyridin-3-yl]carbamate (263 mg, 0.805 mmol), 1-(5-ethyl-4-phenyl-1,3-thiazol-2-yl)piperazine (200 mg, 0.732 mmol) and diisopropylethylamine (0.255 ml, 1.46 mmol) in dimethylsulfoxide (2.5 ml) was stirred at 70° C. for 15 hours. Water was poured into the reaction solution, and the mixture was extracted with ethyl acetate. The extract was washed with water and dried over anhydrous magnesium sulfate, and the solvent was distilled off under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate) and recrystallized from a mixed solvent of hexane and tetrahydrofuran to give the desired product (90.1 mg, 27.3%) as a solid.
