Reaktionsschritte
3′-Bromomethyl-biphenyl-2-carboxylic acid ethyl ester was synthesized as described for 4′-bromomethyl-biphenyl-3-carboxylic acid ethyl ester. 3′-Methyl-biphenyl-2-carboxylic acid ethyl ester (4.3 g, 17.89 mmol, 1 eq.) in carbon tetrachloride was treated with N-bromosuccinimide (3.82 g, 21.47 mmol, 1.2 eq.) and 2,2′-azobisisobutyronitrile (0.15 g, 0.89 mmol, 5 mol %). When complete, the reaction was worked up as described leaving a tan oil.
