Reaction Steps

A mixture comprising t-butyl {4-[3-(3,5-dichlorophenyl)-3-(trifluoromethyl)-pyrrolidin-1-yl]-2-(trifluoromethyl)benzyl}carbamate (6.0 g), concentrated hydrochloric acid (20 mL) and ethanol (100 mL) was stirred at 50° C. for three hours. After cooling the mixture to room temperature, the reaction solution was diluted by adding water (150 mL) and ethyl acetate (150 mL). By adding sodium carbonate in small portions, the solution was neutralized. After the extraction using ethyl acetate, the organic layer was washed with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated off under reduced pressure to obtain the title compound (5.2 g).
