Procedure

In an analogous manner to that described in Example 1(g), by alkylating tert-butyl (1RS,2RS,3RS,5SR)-3-(4-hydroxymethyl-phenyl)-2-(naphthalen-2-ylmethoxy)-8-aza-bicyclo[3.2.1]octane-8-carboxylate [Example 86(eee)] with benzyl bromide there was obtained tert-butyl (1RS,2RS,3RS,5SR)-3-(4-benzyloxymethyl-phenyl)-2-(naphthalen-2-ylmethoxy)-8-aza-bicyclo[3.2.1 ]octane-8-carboxylate, which was used as the crude product in the reaction for BOC cleavage.
