실험 절차

3′-(2-Hydroxy-ethylsulfanylmethyl)-biphenyl-4-carboxylic acid ethyl ester was synthesized as described for 4′-(2-hydroxy-ethylsulfanylmethyl)-biphenyl-3-carboxylic acid ethyl ester. 3′-Bromomethyl-biphenyl-4-carboxylic acid ethyl ester (4.98 g, 15.6 mmol, 1 eq) in anhydrous DMF was treated with 2-mercaptoethanol (2.44 g, 31.20 mmol, 2 eq.) and potassium carbonate (6.47 g, 46.80 mmol, 3 eq.). When complete, the reaction was worked up as described leaving a yellow oil.
