Versuchsvorschrift

N-[4-Chloro-5-({2-[(chloroacetyl)amino][1,3]thiazolo[5,4-b]pyridin-5-yl}oxy)-2-fluorophenyl]-3-(1-cyano-1-methylethyl)benzamide synthesized above was dissolved in tetrahydrofuran (3.0 mL), triethylamine (171 μL, 1.25 mmol) and 1-methylpiperazine (138 μL, 1.25 mmol) were added, and the mixture was stirred at 60° C. for 4 hr. The reaction mixture was cooled to room temperature, diluted with ethyl acetate (30 mL), washed with water (30 mL) and saturated brine (30 mL), and dried over anhydrous sodium sulfate. The insoluble material was filtered off, and the filtrate was concentrated under reduced pressure. The residue was purified by basic silica gel column chromatography (ethyl acetate/methanol=100/0→85/15), and the obtained solution was concentrated under reduced pressure. The residue was recrystallized from ethyl acetate/hexane to give the title compound (193 mg, 75%) as a colorless powder.
