실험 절차

In a manner analogous to that described in Example 1, from [1-(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthyl)propyl]-triphenylphosphonium bromide and 4-ethoxycarbonyl-benzaldehyde there can be obtained p-[(E)-2-(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthyl)-1-butenyl]-benzoic acid ethyl ester of melting point 82°-83° C.
