Reaction Steps

NaH (0.0075 g, 0.19 mmol, 60% dispersion) was added to N-(3-methyl-5-(1H-pyrazol-4-yl)phenyl)-4-(trifluoromethyl)pyrimidin-2-amine (0.02 g, 0.06 mmol) suspended in DMF (1 mL, 0.06 mmol). The reaction mixture was allowed to stir at ambient temperature for 15 minutes. Styrene oxide (0.01 g, 0.08 mmol) was then added. The vial was capped and allowed to stir at 45° C. for 12 hours. H2O (0.2 mL) was added and the reaction was concentrated under reduced pressure. The residue was taken up in DMSO (1.0 mL) and was passed through a syringe filter. The eluent was purified by reverse phase HPLC (0 to 95% ACN/water with 0.1% formic acid modifier) to afford racemic 2-(4-(3-methyl-5-((4-(trifluoromethyl)pyrimidin-2-yl)amino)phenyl)-1H-pyrazol-1-yl)-1-phenylethanol. MS ESI calcd. for C23H21F3N5O [M+H]+ 440. found 440. 1H NMR (600 MHz, DMSO-d6) δ 10.05 (s, 1H), 8.77 (d, J=4.8, 1H), 7.91 (s, 1H), 7.75 (s, 1H), 7.72 (s, 1H), 7.34-7.27 (m, 5H), 7.25-7.19 (m, 2H), 7.01 (s, 1H), 5.69 (d, J=4.6, 1H), 4.94 (d, J=5.2, 1H), 4.20 (d, J=6.4, 2H), 2.26 (s, 3H).
