反応手順
In an analogous manner to that described in Example 44 (e), by alkylating tert-butyl (3RS,4RS)-3-hydroxy-4-(4-hydroxy-phenyl)-piperidine-1-carboxylate [Example 46 (b)] with 1-bromo-3-phenyl-propane in the presence of potassium carbonate, tert-butyl (3RS,4RS)-3-hydroxy-4-[4-(3-phenyl-propoxy)-phenyl]-piperidine-1-carboxylate, alkylation of which analogously to Example 1 (g) with 2-bromomethyl-naphthalene yielded tert-butyl (3RS,4RS)-3-(naphthalen-2-ylmethoxy)-4-[4-(3-phenyl-propoxy)-phenyl]-piperidine-1-carboxylate as a colourless solid; MS: 551 (M)+.
