Versuchsvorschrift
Proceeding as in Reference 19, but substituting 4-benzyloxy-3-bromo-5-formyl-benzoic acid methyl ester (1.0 g, 2.71 mmol) and 5-fluoro-2-methoxyphenyl boronic acid (0.691 g, 4.16 mmol), gave 6-benzyloxy-5′-fluoro-5-formyl-2′-methoxybiphenyl-3-carboxylic acid methyl ester (0.620 g).
