Reaction Steps

To a mixture of 4,4-difluoro-1-(2-methylpyrimidin-5-yl)cyclohexanecarbonitrile (1.2 g, 5.1 mmol) in MeOH/H2O (20 mL, 1:1) was added NaOH (612 mg, 15.3 mmol) and heated to 100° C. overnight. The MeOH was removed in vacuo. The aqueous layer was extracted with EtOAc (3×30 mL) and the organic layers was discarded. The aqueous layer was adjusted pH to 3˜4 with 3N HCl and extracted with EtOAc (3×30 mL). The organic layer was dried over Na2SO4 and concentracted to give 4,4-difluoro-1-(2-methylpyrimidin-5-yl)cyclohexanecarboxylic acid (1.2 g, yield: 92%). 1H NMR (CDCl3 400 MHz): δ8.81 (s, 2H), 2.80-2.60 (m, 5H), 2.20-2.00 (m, 6H).
