Reaction Steps

600 mg (1.84 mmol) of 4′-(2,4-dioxo-thiazolidin-5-ylidenemethyl)biphenyl-3-carboxylic acid (prepared in Example 23(c)), 5 ml of dimethylformamide, 340 mg (2.5 mmol) of 1-hydroxybenzotriazole and 250 μl (2.3 mmol) of benzylamine are introduced into a three-necked flask under a stream of nitrogen. At 0° C., 480 mg (2.5 mmol) of 1-(3-dimethylaminopropyl)-3-ethyl-carbodiimide hydrochloride are added portionwise. The mixture is stirred for 24 hours while allowing the temperature to rise. The reaction medium is immersed in water, extracted with ethyl acetate, dried over magnesium sulfate, filtered and evaporated. The residue obtained is washed with dichloromethane and filtered. 460 mg (60%) of the desired product are obtained.
