Reaction Steps

In 6 mL of dioxane, tert-butyl (1-(3-ethoxy-5-methylphenyl)-3-(trifluormethyl)-1H-pyrazol-5-yl)methylcarbamate (354 mg, 0.886 mmol) was dissolved and hydrogen chloride in dioxane (1.44 mL, c=4 mol/L, 5.76 mml, 6.5 equiv.) was added. The reaction mixture was stirred overnight and filtered, the filtercake was washed with dioxane (2×15 mL) and dried to give (1-(3-ethoxy-5-methylphenyl)-3-(trifluoromethyl)-1H-pyrazol-5-yl)methanamine hydrochloride (211 mg, 71%).
