Procedure

By reacting tert-butyl (3SR,4RS,5RS)-4-[4-(3-benzyloxy-propoxy)-phenyl]-3-hydroxymethyl-5-(naphthalen-2-ylmethoxy)-piperidine-1-carboxylate [Example 148 (h)] with mesyl chloride according to a method known from the literature there was obtained tert-butyl (3SR,4RS,5RS)-4-[4-(3-benzyloxy-propoxy)-phenyl]-3-methanesulphonyloxymethyl-5-(naphthalen-2-ylmethoxy)-piperidine-1-carboxylate [MS: 707 (M+NH4)+ ] as a colourless solid. Further reaction with diethylamine in acetonitrile at 50° C. analogously to Example 34 gave tert-butyl (3RS,4RS,5RS)-4-[4-(3-benzyloxy-propoxy)-phenyl]-3-diethylaminomethyl-5-(naphthalen-2-ylmethoxy)-piperidine-1-carboxylate as a brown foam; MS: 667 (M+H)+.
