Participants

Reaction Steps

3′-(2-Phenoxy-ethylsulfanylmethyl)-biphenyl-2-carboxylic acid (4-dimethylamino-butyl)-amide was synthesized as described for 4′-(2-phenoxy-ethylsulfanylmethyl)-biphenyl-3-carboxylic acid (3-dimethylamino-propyl)-amide. 3′-(2-Phenoxy-ethylsulfanylmethyl)-biphenyl-2-carboxylic acid (0.95 g, 2.61 mmol, 1 eq.) in anhydrous THF was treated with 1,1-carbonyldiimidazole (0.43 g, 2.66 mmol, 1.02 eq.) and 4-dimethylaminobutylamine (0.36 g, 3.13 mmol, 1.2 eq.) as described. When complete, the reaction was worked up as described leaving a yellow oil.
