実験手順

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) in tetrahydrofuran (20 mL) were added acetyl chloride (63 mg, 0.80 mmol) and pyridine (86 mg, 1.09 mmol), and the mixture was stirred at room temperature for 10 min. To the reaction mixture were added water (100 mL) and ethyl acetate (100 mL). After stirring for 30 min, the mixture was extracted with ethyl acetate. The organic layer was 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 (105 mg, 28%) as a colorless solid.
