Reaction Steps

To a solution of ethyl 4-{[2-({3-[2-(1-hydroxycyclobutyl)-1,3-thiazol-5-yl]-5-methylphenyl}-amino)pyrimidin-4-yl]oxy}cyclohexanecarboxylate (Example 94A-16, 40 mg, 0.08 mmol) in tetrahydrofuran (0.52 mL), water (0.13 mL), and methanol (0.13 mL) was added aqueous sodium hydroxide (1.0 M in H2O, 0.2 mL, 0.2 mmol). The mixture was stirred at room temperature until complete. The reaction was then quenched with aqueous hydrochloric acid (1.0 M in H2O, 0.22 mL, 0.22 mmol). The resulting mixture was extracted with dichloromethane. The organic layer was dried over sodium sulfate, filtered, and concentrated under reduced pressure to provide 4-{[2-({3-[2-(1-hydroxycyclobutyl)-1,3-thiazol-5-yl]-5-methylphenyl}amino)pyrimidin-4-yl]oxy}cyclohexanecarboxylic acid (37 mg, 0.08 mmol, 99%) as a pale yellow solid.
