Reaction Steps

A 25 mL round bottom flask was charged with 65 mg (0.164 mmol) of N-(2-hydroxyacetyl)-5-(4-piperidyl)-4-(4-pyrimidyl)-3-(4-chlorophenyl)pyrazole and 2.5 mL of dioxane. To this suspension was added 0.082 mL of 4 N HCl in dioxane. The mixture was stirred for 2 hours. The mixture was diluted with 5 mL of Et2O and filtered. The solid was dried over solid CaSO4 under vacuum for 12 h to afford 68 mg of N-(2-hydroxyacetyl)-5-(4-piperidyl)-4-(4-pyrimidyl)-3-(4-chlorophenyl)pyrazole hydrochloride. 1H NMR (DMSO-d6) 9.18 (s, 1H), 8.63 (d, J=5.37 Hz, 1H), 7.40 (d, J=8.59 Hz, 2H), 7.33 (d, J=8.59 Hz, 2H), 7.15 (m, 1H), 4.40 (m, 1H), 4.06 (m, 2H), 3.72 (m, 1H), 3.33 (m, 1H), 2.97 (m, 1H), 2.62 (m, 1H), 1.83 (m, 2H), 1.64 (m, 2H); MS (M+H): 398.
