Participants

Reaction Steps

2′-(2-Phenoxy-ethylsulfanylmethyl)-biphenyl-3-carboxylic acid (2-dimethylamino-ethyl)-amide was synthesized as described for 4′-(2-phenoxy-ethylsulfanylmethyl)-biphenyl-3-carboxylic acid (3-dimethylamino-propyl)-amide. 2′-(2-Phenoxy-ethylsulfanylmethyl)-biphenyl-3-carboxylic acid (1.0 g, 2.74 mmol, 1 eq.) in anhydrous THF was treated with 1,1-carbonyldiimidazole (0.45 g, 2.79 mmol, 1.02 eq.) followed by N,N-dimethylethylenediamine (0.29 g, 3.29 mmol, 1.2 eq.) as described. When complete, the reaction was worked up as described leaving a yellow oil.
