Participants

Reaction Steps

1.28 g (0.0127 mol) of 4-hydroxypiperidine were dissolved in 60 ml of dimethylformamide and cooled to 0°. 3.0 g (0.0159 mol) of 3-fluoro-benzyl bromide and 5.0 ml (0.0349 mol) of triethylamine were added under argon and the mixture was left to come to room temperature. It was stirred for 16 hrs., the solvent was distilled off and the residue was chromatographed on silica gel with dichloromethane/methanol (19:1) as the eluent. 1.19 g (36%) of 1-(3-fluoro-benzyl)-piperidin-4-ol was obtained as yellow crystals; m.p. 61°-62°.
