Versuchsvorschrift

To a solution of N-{3-[(2-amino-1,3-benzothiazol-6-yl)oxy]-4-fluorophenyl}-2-chloro-3-(1-cyano-1-methylethyl)benzamide (350 mg, 0.73 mmol) produced in Example A47(ii) in tetrahydrofuran (20 mL) were added cyclopropanecarbonyl chloride (114 mg, 1.09 mmol) and pyridine (86 mg, 1.09 mmol), and the mixture was stirred at room temperature for 30 min. Water (100 mL) and ethyl acetate (100 mL) were added to the reaction mixture, and the mixture was stirred for 30 min. The organic layer was separated, and dried over anhydrous magnesium sulfate. The insoluble material was filtered off, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel chromatography (hexane/ethyl acetate=20/80→0/100), and triturated with ethyl acetate/hexane to give the title compound (162 mg, 40%) as a colorless solid.
