Procedure
4′-(2-Phenoxy-ethylsulfanylmethyl)-biphenyl-4-carboxylic acid ethyl ester was prepared as described for 4′-(2-phenoxy-ethylsulfanylmethyl)-biphenyl-3-carboxylic acid ethyl ester. 4′-(2-Hydroxy-ethylsulfanylmethyl)-biphenyl-4-carboxylic acid ethyl ester (3.11 g, 9.83 mmol, 1 eq.) in anhydrous THF (100 mL) was treated with phenol (1.29 g, 13.76 mmol, 1.4 eq.), triphenylphosphine (3.61 g, 13.76 mmol, 1.4 eq.), and diisopropyl azidocarboxylate (2.78 g, 2.71 mL, 13.76 mmol, 1.4 eq.) as described. When the reaction was complete, the reaction was worked up and the product purified via silica gel flash chromatography leaving 4′-(2-phenoxy-ethylsulfanylmethyl)-biphenyl4-carboxylic acid ethyl ester (3.82 g, 99% yield) as a yellow oil.
