Reaction Steps

A mixture of 2,2,2-trichloroethyl (3,4-dimethylisoxazol-5-yl)carbamate (201 mg, 0.700 mmol), 1-[4-(2,4-dichlorophenyl)-1,3-thiazol-2-yl]piperazine (200 mg, 0.636 mmol) and diisopropylethylamine (0.222 ml, 1.27 mmol) in dimethyl sulfoxide (2.5 ml) was stirred at 70° C. for 3 days. Water was poured to the reaction mixture, 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 recrystallized from a mixed solvent of hexane and tetrahydrofuran to give 116 mg (40.3%) of the desired product as a solid.
