22.5 Ml of benzyl bromide was added dropwise to a stirred solution of 32.3 g of 3,4-epoxy-4-phenylpiperidine and 38.1 ml of triethylamine in 254 ml of benzene. A precipitate appeared during the addition. The whole reaction mixture was then stirred at room temperature for three hours. The residual solid was removed by filtration and the solvent evaporated to give 53.4 g of 1-benzyl-3,4-epoxy-4-phenyl-piperidine.
