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 3-methyl-4-ethoxycarbonyl-benzaldehyde there can be obtained p-[(E)-2-(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthyl)propenyl]-2-methyl-benzoic acid ethyl ester as a colourless oil which is uniform according to thin-layer chromatography, (Rf=0.6; hexane/15% ether).
