Participants

Reaction Steps

Sodium cyanide (113 mg, 2.3 mmol) was added to 4-methyl-6-(1-((2-methyloxiran-2-yl)methyl)-1H-pyrazol-4-yl)-N-(4-(trifluoromethyl)pyridin-2-yl)pyridin-2-amine (180 mg, 0.46 mmol) in ethanol (5 mL) and water (3 mL), and the mixture was stirred at room temperature for 18 h. The mixture was passed through CELITE, washed with methanol, and concentrated under reduced pressure. The resultant residue was purified by column chromatography on silica gel (0-20% EtOAc/Hexane) to afford 3-hydroxy-3-methyl-4-(4-(4-methyl-6-((4-(trifluoromethyl)pyridin-2-yl)amino)pyridin-2-yl)-1H-pyrazol-1-yl)butanenitrile. The racemic mixture was purified by chiral SFC (Chiralpak column, MeOH+0.25% DMEA) to afford (S or R)-3-hydroxy-3-methyl-4-(4-(4-methyl-6-((4-(trifluoromethyl)pyridin-2-yl)amino)pyridin-2-yl)-1H-pyrazol-1-yl)butanenitrile (Isomer 1, first eluting): MS ESI calc'd. for C20H20F3N6O [M+H]+ 417. found 417. 1H NMR (500 MHz, DMSO-d6) δ 10.07 (s, 1H), 8.61 (s, 1H), 8.46 (d, J=5 Hz, 1H), 8.15 (s, 1H), 7.96 (s, 1H), 7.17 (d, J=5 Hz, 1H), 7.11 (s, 1H), 7.02 (s, 1H), 5.55 (s, 1H), 4.15 (s, 2H), 2.71-2.64 (m, 2H), 2.28 (s, 3H), 1.18 (s, 3H).
