実験手順
4-[3-(2-Benzylphenyl)prop-1-enyl]benzoic acid was prepared by reaction of 2-benzylbenzaldehyde with 4-carboxyphenethyltriphenylphosphonium bromide using a similar method to that of example 33(B) to give a gum. [2-Benzylbenzaldehyde (an oil) was obtained from 2-benzylbenzoic acid using a similar method to that of example 33(A)].
