Participants

Reaction Steps

In 9 mL of dioxane, tert-butyl (1-(4-fluorophenyl)-3-(trifluoromethyl)-1H-pyrazol-5-yl)methylcarbamate (501 mg, 1.39 mmol) was dissolved and hydrogen chloride in dioxane (2.27 mL, c=4 mol/L, 9.06 mml, 6.5 equiv.) was added. The reaction mixture was stirred overnight and filtered, the filter cake was washed with ether (2×15 mL) and dried to give (1-(4-fluorophenyl)-3-(trifluoromethyl)-1H-pyrazol-5-yl)methanamine hydrochloride (188 mg, 46%).
