Procedure

0.31 g (0.0015 mol) of 1-(4-methyl-benzyl)-piperidin-4-ol and 0.52 ml (0.00375 mol) of triethylamine were dissolved in 15 ml of toluene, treated with 0.25 ml (0.00215 mol) of benzoyl chloride and boiled at reflux for 18 hrs. The reaction mixture was concentrated and the residue was chromatographed over silica gel with ethyl acetate/hexane (1:4). 0.295 g (64%) of 1-(4-methyl-benzyl)-piperidin-4-yl benzoate was obtained as a yellow oil.
