Hydrochloric Acid → (4-Fluorophenyl)(3-hydroxypiperidin-1-yl)methanone

Participants

Reaction Steps

A mixture of 3-hydroxypiperidine (0.6 g, 5.93 mmol), 4-fluorobenzoic acid (0.83 g, 5.93 mmol), HOBT (0.8 g, 5.93 mmol), EDCI.HCl (1.7 g, 8.9 mmol) and dry triethylamine (1.66 mL, 11.86 mmol) in dry dichloromethane (30 mL) was kept under stiffing overnight at ambient temperature, under nitrogen atmosphere. HCl 1N (30 mL) was then added and the phases separated. The organic layer was washed with HCl 1N (30 mL), with NaOH 1N (30 mL×2 times), then with water (30 mL). Evaporation of the organic solvent afforded (4-fluoro-phenyl)-(3-hydroxy-piperidin-1-yl)-methanone as a white oil (0.7 g).
