実験手順

0.27 g (0.001 mol) of 1-(4-bromo-benzyl)-piperidin-4-ol and 0.359 ml (0.0025 mol) of triethylamine were dissolved in 10 ml of toluene, treated with 0.16 ml (0.00125 mol) of 4-chlorobenzoyl 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). 0.333 g (81.5%) of 1-(4-bromo-benzyl)-piperidin-4-yl 4-chloro-benzoate was obtained as a colorless oil.
