Trifluoroacetic acid → 3-(Piperidin-4-ylmethyl)pyridine

Participants

Reaction Steps

A solution of 1-(1,1-dimethylethyloxycarbonyl)-4-(3-pyridylmethyl)piperidine (500 mg, 1.80 mmol) in chloroform (14 mL) was cooled to 0° C. and treated with trifluoroacetic acid (5 mL, 65.14 mmol). The resulting mixture was stirred for 1 h and then made basic by addition of aqueous sodium hydroxide. The organic extracts were separated and the aqueous was reextracted three more times with chloroform. The chloroform extracts were combined, dried over sodium sulfate, filtered and concentrated on a rotary evaporator to give the title compound as a colorless oil (300 mg, 1.70 mmol, 95%).
