Sodium hydride (23.5 mg, 0.59 mmol) at 0° C. was added to an oven-dried vial containing N-[3-methyl-5-(1H-pyrazol-4-yl)phenyl]-4-(trifluoromethyl)pyrimidin-2-amine (75 mg, 0.24 mmol) in DMF (0.8 mL). The mixture was stirred for 10 minutes, and then methyl 2-methylglycidate (0.03 mL, 0.24 mmol) was added. The reaction was warmed to room temperature and stirred overnight, followed by subsequent heating to 70° C. overnight. The mixture was cooled to room temperature, diluted with EtOAc, washed with water (3×), then brine, dried over sodium sulfate, filtered, and concentrated under reduced pressure. The residue was purified by reverse phase HPLC (45 to 85% ACN/water with 0.1% TFA modifier) to afford racemic 2-hydroxy-2-methyl-3-[4-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1H-pyrazol-1-yl]propanoic acid. MS ESI calcd. for C19H18F3N5O3 [M+H]+ 422. found 422.
