Substituted biphenyl-2-carboxaldehydes are prepared in good yield by reacting palladium complexes of substituted benzaldehyde aniline Schiff bases with substituted phenylmagnesium bromides in the presence of at least six, preferably eight, molar equivalents of triphenylphosphine. Those compounds are intermediates for synthetic, in vivo cholesterol synthesis inhibitors.
