Procedure

0.382 g (0.001825 mol) of 1-(2-fluoro-benzyl)-piperidin-4-ol and 0.512 ml (0.00365 mol) of triethylamine were dissolved in 10 ml of toluene, treated with 0.483 ml (0.00365 mol) of p-toluoyl 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 (1:2). 0.48 g (80%) of 1-(2-fluoro-benzyl)-piperidin-4-yl 4-methyl-benzoate was obtained as a yellow oil. MS: me/e=328 (C20H23 FN02+).
