Sodium borohydride → HCID 178428310, compound

Participants

Reaction Steps

Sodium borohydride (3.39 mg, 0.09 mmol) was added to 4-[4-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1H-pyrazol-1-yl]cyclohexanone (24.8 mg, 0.06 mmol) dissolved in methanol (0.5 mL). The reaction mixture was stirred at room temperature for one hour. The mixture was diluted with EtOAc, washed with water, dried over sodium sulfate, filtered, and concentrated under reduced pressure. The residue was purified by reverse phase HPLC (45 to 80% ACN/Water with 0.1% TFA modifier). The free base was liberated using PL-HCO3 cartridges (Stratospheres™, 0.9 mmol) and lyophilized to afford cis-4-[4-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1H-pyrazol-1-yl]cyclohexanol. MS ESI calcd. for C21H23F3N5O [M+F]+ 418. found 418. 1H NMR (500 MHz, DMSO-d6) δ 10.10 (s, 1H), 8.80 (d, J=4.7 Hz, 1H), 8.06 (s, 1H), 7.82 (s, 1H), 7.70 (s, 1H), 7.38 (s, 1H), 7.25 (d, J=4.7 Hz, 1H), 7.05 (s, 1H), 4.67 (s, 1H), 4.19-4.07 (m, 1H), 3.50-3.41 (m, 1H), 2.27 (s, 3H), 2.02-1.99 (m, 2H), 1.94-1.85 (m, 2H), 1.78 (q, J=11.7 Hz, 2H), 1.35 (q, J=11.7 Hz, 2H).
