Procedure

A solution of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (0.095 g) in methylene chloride (5 ml) was added to a stirred mixture of 3-(3,4-dimethoxybenzamido)-4-methylbenzoic acid (0.157 g), 2-(4-chlorophenoxy)ethylamine (C. Chim. Ther., 1973, 8, 259; 0.086 g), 4-dimethylaminopyridine (0.007 g), 1-hydroxybenzotriazole (0.074 g) and methylene chloride (5 ml). The resultant mixture was stirred at ambient temperature for 16 hours. The mixture was evaporated and the residue was partitioned between ethyl acetate and a saturated aqueous sodium bicarbonate solution. The organic phase was washed with an aqueous citric acid solution, dried over magnesium sulphate and evaporated. There was thus obtained the title compound as a solid (0.158 g); Mass Spectrum: M+H+ 469.
