5-[2,6-Difluoro-4-(1-hydroxy-1-methylethyl)phenyl]-2-({2-[2-(trimethylsilyl)ethoxy]pyrimidin-4-yl}amino)thiophene-3-carboxamide (109 mg, 0.215 mmol) was stirred in a mixture of MeOH (10 mL) and 2N HCl (6 mL) at room temperature overnight. The solvent was removed in vacuo, saturated NaHCO3 was added and the reaction mixture was extracted with EtOAc (2×). The combined organic extracts were washed with brine, dried over MgSO4, filtered, and concentrated in vacuo. Purification of the residue by reverse phase HPLC (40-100% MeCN—H2O) gave the title compound as a pale yellow solid after triturating in DCM.
