2-Chloromethyl-1,4-dimethoxy-naphthalene → tert-butyl (3'RS,4'RS)-3'-(1,4-dimethoxy-naphthalen-2-ylmethoxy)-6-methylsulfanyl-3',4',5',6'-tetrahydro-2'H-[3,4']bipyridine-1'-carboxylate

Reaction Steps

In an analogous manner to that described in Example 125 (g), from tert-butyl (3'RS,4'RS)-3'-hydroxy-6-methylsulphanyl-3',4',5',6'-tetrahydro-2'H-[3,4']bipyridine-1'-carboxylate by alkylation with 2-chloromethyl-1,4-dimethoxy-naphthalene [J. Amer. Chem. Soc. 64, 2657 (1942)] there was obtained tert-butyl (3'RS,4'RS)-3'-(1,4-dimethoxy-naphthalen-2-ylmethoxy)-6-methylsulphanyl-3',4',5',6'-tetrahydro-2'H-[3,4']bipyridine-1'-carboxylate in the form of a colourless solid; MS: 526 (M+H)+.
