Participants

Reaction Steps

A solution of 2,2,2-trichloroethyl [2-(acetylamino)pyrimidin-5-yl]carbamate (60.0 mg, 0.187 mmol), 1-(4-phenyl-1,3-thiazol-2-yl)piperazine (44.9 mg, 0.183 mmol), diisopropylethylamine (0.0319 ml, 0.183 mmol) and dimethylsulfoxide (2 ml) was stirred at 80° C. for 4 hours, the reaction mixture was poured into water and the mixture was extracted with ethyl acetate. The extract was washed with water and dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure. The residue was recrystallized from a mixed solvent of tetrahydrofuran, ethyl acetate and hexane to obtain the desired product (31.0 mg, 40.0%) as a solid.
