Participants

Reaction Steps

A solution of tert-butyl[3-({2-[(cyclopropylcarbonyl)amino][1,3]thiazolo[5,4-b]pyridin-5-yl}oxy)phenyl]carbamate (900 mg, 2.11 mmol) and anisole (1 mL) in trifluoroacetic acid (10 mL) was stirred at 0° C. for 1 hr. The reaction mixture was concentrated under reduced pressure, saturated aqueous sodium hydrogen carbonate solution (50 mL) was added to the residue, and the mixture was extracted with tetrahydrofuran-ethyl acetate mixture (1:1, 50 mL, 15 mL). The combined organic layer was washed with saturated brine (5 mL), and dried over anhydrous sodium sulfate. The insoluble material was filtered off, and the filtrate was concentrated under reduced pressure. The obtained residue was washed with a tetrahydrofuran-ethyl acetate mixture to give the title compound (542 mg, 79%) as a pale-yellow solid.
