반응 단계

A mixture of 2,2,2-trichloroethyl pyridazin-3-ylcarbamate (250 mg, 0.922 mmol), 4-[4-(3-fluorophenyl)-1,3-thiazol-2-yl]piperidine (220 mg, 0.839 mmol) and diisopropylethylamine (0.292 ml, 1.68 mmol) in dimethylsulfoxide (2.8 ml) was stirred at 70° C. for 6 hours. Water was poured into the reaction solution, 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 (ethyl acetate) and recrystallized from a mixed solvent of hexane and ethyl acetate to give the desired product (141 mg, 43.7%) as a solid.
