実験手順
To a solution of tert-butyl 4-(4-(5-amino-2-(2,6-difluorophenyl)thiazole-4-carboxamido)isothiazol-5-yloxy)piperidine-1-carboxylate (1A) (10 mg, 0.02 mmol) in CH2Cl2 (1 mL) at room temperature (25° C.) was added TFA (trifluoroacetic acid) (0.5 mL), stirred for 10 min and then concentrated in vacuo at room temperature (25° C.) to afford the product 5-amino-2-(2,6-difluorophenyl)-N-(5-(piperidin-4-yloxy)isothiazol-4-yl)thiazole-4-carboxamide (1) (5 mg, 0.011 mmol)
