実験手順

To a solution of tert-butyl {5-[(2-amino[1,3]thiazolo[5,4-d]pyrimidin-5-yl)amino]-4-chloro-2-fluorophenyl}carbamate (470 mg, 1.14 mmol) in pyridine (10 mL) was added acetyl chloride (204 μL, 2.86 mmol), and the mixture was stirred at room temperature for 1 hr. To the reaction mixture was added saturated aqueous sodium hydrogen carbonate solution (50 mL), and the mixture was extracted with ethyl acetate/tetrahydrofuran mixture (1:1, 50 mL, 20 mL). The combined organic layer was washed with saturated brine (10 mL), and dried over anhydrous sodium sulfate. The insoluble material was filtered off, and the filtrate was concentrated under reduced pressure to give tert-butyl(5-{[2-(acetylamino)[1,3]thiazolo[5,4-d]pyrimidin-5-yl]amino}-4-chloro-2-fluorophenyl)carbamate as a brown amorphous solid. The obtained compound was used for the next reaction without further purification.
