実験手順
In accordance with the same procedures as in Example 1, part (b), starting with 2-methyl-6-bromonaphthalene (2.21 g, 10 mmoles) and 5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-bromonaphthalene (3.20 g, 12 mmoles), there is obtained after column chromatography (9 hexane, 1 dichloromethane) 2-methyl-6-(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthyl)naphthalene (2.38 g, 72%) having a melting point of 173°-175° C.
