実験手順

A solution of 3-[(2-amino-1,3-benzothiazol-6-yl)oxy]-N-[3-(trifluoromethyl)phenyl]benzamide (429 mg, 1.0 mmol) produced in Example A29(v) and chloroacetyl chloride (225 mg, 2.0 mmol) in N,N-dimethylformamide (10 mL) was stirred at room temperature for 6 hr. The reaction mixture was poured into water and the mixture was extracted with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate, the solvent was evaporated under reduced pressure, and the residue was purified by silica gel chromatography (eluent:hexane/ethyl acetate=1:1) to give a colorless oil. This was dissolved in N,N-dimethylformamide (5 mL), 1-methylpiperazine (400 mg, 4.0 mmol) was added, and the mixture was stirred at room temperature for 1 hr. The reaction mixture was poured into water and the mixture was extracted with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by basic silica gel chromatography (eluent:ethyl acetate/methanol=10:1), and triturated with diethyl ether to give the title compound (340 mg, 60%) as a white solid.
