Procedure

To a solution of N-{5-[(2-amino[1,3]thiazolo[5,4-b]pyridin-5-yl)oxy]-2-fluorophenyl}-2-chloro-3-(1-cyanocyclopropyl)benzamide (9.0 g, 18.8 mmol) and pyridine (2.3 mL, 28.1 mmol) in tetrahydrofuran (90 mL) was added dropwise cyclopropanecarbonyl chloride (1.89 mL, 20.8 mmol) under ice-cooling, and the mixture was stirred at room temperature for 3 hr. Cyclopropanecarbonyl chloride (63 μL, 0.69 mmol) was further added and the mixture was stirred at room temperature for 12 hr. Water (100 mL) and saturated aqueous sodium hydrogen carbonate solution (100 mL) were added to the reaction mixture to give a suspension, and the mixture was stirred at room temperature for 30 min. The precipitate was collected by filtration, repeatedly washed with water, and dried under reduced pressure to give the title compound (9.85 g, 96%) as a white powder.
