Participants

Reaction Steps

1.41 g (0.01389 mol) of 4-hydroxypiperidine were dissolved in 60 ml of dimethylformamide and cooled to 0°. 3.0 g (0.01389 mol) of 3-nitrobenzyl bromide and 4.3 ml (0.03056 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 taken up in dichloromethane. The organic phase was washed with water and saturated sodium chloride solution, dried over magnesium sulfate and concentrated and the residue was chromatographed on silica gel with dichloromethane/methanol (19:1) as the eluent. 1.9 g (58%) of 1-(3-nitro-benzyl)-piperidin-4-ol were obtained as a yellow oil. MS: me/e=237 (C12H17N2O3+)
