Reaction Steps

A mixture of 2,2,2-trichloroethyl (3-methylisothiazol-5-yl)carbamate (259 mg, 0.893 mmol), 1-(3-phenyl-1,2,4-thiadiazol-5-yl)piperazine (200 mg, 0.812 mmol) and diisopropylethylamine (0.156 ml, 0.893 mmol) in dimethylsulfoxide (2.7 ml) was stirred at 70° C. for 20 hours. Water was poured into 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 purified by silica gel column chromatography (hexane:ethyl acetate=3:7) and recrystallized from a mixed solvent of hexane and tetrahydrofuran to obtain the desired product (92.7 mg, 29.5%) as a solid.
