실험 절차
A mixture of 14.2 parts of (phenylmethyl) 4-(methoxymethyl)-4-(phenylamino)-1-piperidinecarboxylate and 170.2 parts of ethyl carbonochloridate is stirred and refluxed for 16 hours in an oil-bath at 110° C. The reaction mixture is evaporated and the residue is dissolved in 225 parts of trichloromethane. The solution is washed twice with water, dried, filtered and evaporated. The residue is dissolved in methylbenzene and the latter is evaporated again, yielding 14.2 parts (83.5%) of (phenylmethyl) 4-[(ethoxycarbonyl)phenylamino]-4-(methoxymethyl)-1-piperidinecarboxylate as a residue.
