Reaction Steps

In an analogous manner to that described in Example 1(g), by alkylating tert-butyl (3RS,4RS)-4-(4-allyloxy-phenyl)-3-hydroxy-piperidine-1-carboxylate [Example 86(b)] with 2-chloromethyl-1-(2-methoxy-ethoxymethoxy)-naphthalene there was obtained tert-butyl (3RS,4RS)-4-(4-allyloxy-phenyl)-3-[1-(2-methoxy-ethoxymethoxy)-naphthalen-2-ylmethoxy]-piperidine-1-carboxylate, from which by cleavage of the allyl group by means of bis-(triphenylphosphine)-palladium(II) diacetate analogously to Example 152(e) there was obtained tert-butyl (3RS,4RS)-4-(4-hydroxy-phenyl)-3-[1-(2-methoxy-ethoxymethoxy)-naphthalen-2-ylmethoxy]-piperidine-1-carboxylate. Subsequent alkylation with 5-bromomethyl-3-thiophen-2-yl-[1,2,4]oxadiazole analogously to Example 44(e) gave tert-butyl (3RS,4RS)-3-[1-(2-methoxy-ethoxymethoxy)-naphthalen-2-ylmethoxy]-4-[4-(3-thiophen-2-yl-[1,2,4]oxadiazol-5-ylmethoxy)-phenyl]-piperidine-1-carboxylate as a colourless, viscous oil; MS: 702 (M+H)+.
