Procedure

A mixture of 80 mg of methyl p-(p-amidinobenzamidoacetyl)phenoxyacetate (Example 25), 40 mg of potassium carbonate, 10 ml of ethanol and 4 ml of water was stirred at room temperature under argon for 4 hours. 10 ml of water were then added to the mixture, which was neutralized to pH 6 with 1N HCl. It was concentrated to 10 ml in vacuo and left to stand in a refrigerator overnight. The precipitate which had separated out was filtered off with suction and dried over KOH in vacuo at 50° C. 52 mg of amorphous p-(p-amidinobenzamidoacetyl)phenoxyacetic acid were obtained, IR bands (KBr) at 3354, 3286, 3042, 1647, 1598, 1542, 1485, 1422, 1360, 1232, 1177, 994 and 710 cm-1.
