Procedure

In a manner analogous to that described in Example 1, from [1-(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthyl)ethyl]-triphenylphosphonium bromide and 4-isopropyl-benzaldehyde there can be obtained 6-[(E)-p-isopropyl-α-methylstyryl]-1,2,3,4-tetrahydro-1,1,4,4-tetramethylnaphthalene of melting point 86°-87° C.
