Reaction Steps

A mixed solution of tert-butyl 3-{[(2,2,2-trichloroethoxy)carbonyl]amino}piperidine-1-carboxylate (555 mg, 1.48 mmol), 1-(3-phenyl-1,2,4-thiadiazol-5-yl)piperazine (400 mg, 1.62 mmol) and diisopropylethylamine (0.257 ml, 1.48 mmol) in dimethyl sulfoxide (4.9 ml) was stirred at 70° C. for 4 days. Water was poured to the reaction mixture, and the resulting solution 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 ethyl acetate to give 90.9 mg (13.0%) of the desired product as a solid.
