実験手順

tert-Butyl (3R)-3-{[2-({3-methyl-5-[2-(3-oxo-1,4-diazepan-1-yl)-1,3-thiazol-5-yl]-phenyl}amino)pyrimidin-4-yl]oxy}pyrrolidine-1-carboxylate (80 mg, 0.14 mmol) was taken up in dichloromethane (1 mL). The mixture was treated with trifluoroacetic acid (0.2 mL, 2.6 mmol) and left to stir for 1 hour. The reaction was neutralized with saturated aqueous sodium bicarbonate, and extracted with ethyl acetate (×3). The combined organics were washed with brine, dried over sodium sulfate, concentrated, and purified by Combiflash (methanol/dichloromethane) to provide 4-{5-[3-methyl-5-({4-[(3R)-pyrrolidin-3-yloxy]-pyrimidin-2-yl}amino)phenyl]-1,3-thiazol-2-yl}-1,4-diazepan-2-one.
