2-Chloromethyl-1,4-dimethoxy-naphthalene → tert-butyl (3RS,4RS)-3-(1,4-dimethoxy-naphthalen-2-ylmethoxy)-4-[4-(4-phenyl-butoxy)-phenyl]-piperidine-1-carboxylate

Participants

Reaction Steps

In an analogous manner to that described in Example 1 (g), by alkylating tert-butyl (3RS,4RS)-3-hydroxy-4-[4-(4-phenyl-butoxy)-phenyl]-piperidine-1-carboxylate [Example 122 (b)] with 2-chloromethyl-1,4-dimethoxy-naphthalene [J.Org.Chem. (1983), 48(19),3265-3268] there was obtained tert-butyl (3RS,4RS)-3-(1,4-dimethoxy-naphthalen-2-ylmethoxy)-4-[4-(4-phenyl-butoxy)-phenyl]-piperidine-1-carboxylate as a colourless, viscous oil; MS: 626 (M+H)+.
