Trifluoroacetic acid → 2-Fluoro-4-(piperidin-4-ylmethyl)aniline

Participants

Reaction Steps

Tert-butyl 4-(4-amino-3-fluorobenzyl)piperidine-1-carboxylate (6.49 mmol, 2 g) was dissolved in dichloromethane (5 mL). Trifluoroacetic acid (3 mL) was added and the reaction mixture stirred at room temperature for 30 minutes. The reaction mixture was purified by SCX chromatography to give the intermediate 2-fluoro-4-(piperidin-4-ylmethyl)aniline (1.6 g) as a colourless oil.
