Procedure

2′-(2-Phenoxy-ethylsulfanylmethyl)-biphenyl-4-carboxylic acid was synthesized as described for 4′-(2-phenoxy-ethylsulfanylmethyl)-biphenyl-3-carboxylic acid. 2′-(2-Phenoxy-ethylsulfanylmethyl)-biphenyl-4-carboxylic acid ethyl ester (4.75 g, 12.10 mmol, 1 eq.) in 30% aqueous THF was treated with lithium hydroxide (0.87 g, 36.30 mmol, 3 eq.). When complete, the reaction was worked up as described leaving a tan solid.
