A solution of 2,2,2-trichloroethyl {4-[(trifluoroacetyl)amino]phenyl}carbamate (200 mg, 0.527 mmol), 1-(4-phenyl-1,3-thiazol-2-yl)piperazine (129 mg, 0.527 mmol), diisopropylethylamine (0.184 ml, 1.05 mmol) and dimethyl sulfoxide (4 ml) was stirred at 70° C. for 24 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, and the residue was recrystallized from ethyl acetate to give 100 mg (39.8%) of the desired product as a solid.
