Versuchsvorschrift

To a solution of N-{3-[(2-amino-5-fluoro-1,3-benzothiazol-6-yl)oxy]phenyl}-3-(1-cyano-1-methylethyl)benzamide (200 mg, 0.448 mmol) in pyridine (4.0 mL) was added cyclopropanecarbonyl chloride (61 μL, 0.672 mmol), and the mixture was stirred at room temperature for 4 hr. The reaction mixture was diluted with ethyl acetate (100 mL), washed with 5% aqueous sodium hydrogencarbonate solution (100 mL) and saturated brine (100 mL), successively, and dried over anhydrous sodium sulfate. The insoluble material was filtered off, and the filtrate was concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane/ethyl acetate=60/40→0/100), and the obtained solution was concentrated under reduced pressure. The residue was triturated with ethyl acetate/diisopropyl ether/hexane to give the title compound (118 mg, 51%) as a colorless solid.
