Sodium Hydroxide → 4-(5-Fluoro-2-methoxyphenyl)piperidine

Participants

Reaction Steps

The crude product of 1-formyl-4-(5-fluoro-2-methoxy-phenyl)-piperidine (0.80 g, 3.4 mmole) was dissolved in HCl (16 mL, 0.5 N) and MeOH (5 mL), and the mixture was brought to reflux for 16 hours. The mixture was cooled to room temperature and basified with NaOH (2.5 N), and extracted with EtOAc (3×25 mL) to give 4-(5-fluoro-2-methoxy-phenyl)-piperidine which was used directly without further purification.
