Procedure

At ambient temperature, p-toluenesulphonic acid chloride (45.8 mg, 0.24 mmol) is added to a mixture of 3-[2-ethoxy-4-[N-(1-(2-piperidino-phenyl)-1-butyl)-aminocarbonylmethyl]-phenyl]-propionic acid amide, (56 mg, 0.12 mmol) melting point 153°-155° C. [prepared from the corresponding propionic acid by reacting with carbonyldiimidazole and then with ammonia in tetrahydrofuran] and absolute pyridine (0.044 ml). The mixture is stirred for 45 minutes at 20° C. and for 2 hours at 50° to 60° C. After cooling, water is added, the mixture is made alkaline with concentrated ammonia and extracted three times with chloroform. The combined chloroform extracts are washed with water, dried over sodium sulphate, filtered and concentrated evaporation in vacuo. The evaporation residue is purified by column chromatography on silica gel (chloroform/ethyl acetate=9/1).
