Trifluoroacetic acid → 1-{1-[4-(Trifluoromethyl)phenyl]piperidin-4-yl}methanamine

Participants

Reaction Steps

A mixture of trifluoroacetic acid (10 ml) and dichloromethane (10 ml) was added to tert-butyl({1-[4-(trifluoromethyl)phenyl]piperidin-4-yl}methyl)carbamate (1.36 g). This mixture was stirred at room temperature for 3 h. The sample was concentrated and taken up in dichloromethane (20 ml) and saturated aqueous sodium bicarbonate. The mixture was extracted and the organic layer was dried over sodium sulfate, filtered, and concentrated in vacuo to provide the title compound (1.21 g, 86%). Mass spectrum (ESI) 242.1 (M+1).
