HCID 54212852tert-butyl (3RS,4RS)-3-(naphthalen-2-ylmethoxy)-4-[4-(naphthalen-2-ylmethoxymethyl)-phenyl]-piperidine-1-carboxylate

Procedure

In an analogous manner to that described in Example 22(i), by alkylating tert-butyl (3RS,4RS)-3-hydroxy-4-(4-hydroxymethyl-phenyl)-piperidine-1-carboxylate with 2-bromomethylnaphthalene there was obtained tert-butyl (3RS,4RS)-3-(naphthalen-2-ylmethoxy)-4-[4-(naphthalen-2-ylmethoxymethyl)-phenyl]-piperidine-1-carboxylate as a colourless oil, Rf : 0.31 (SiO2, hexane:ethyl acetate=2:1).
