Bis(benzamido)benzoic acid derivs. (I; R1 = hydroxyl, alkyl or amino, R2 = H, acyl or alkyl) were prepd. by the reaction of a diaminobenzoic alkyl with a 2-alkoxybenzoic acid. Thus, 2-MeC6H4COCl reacted with 2,4-(H2N)2C6H3O(CH2)3NET2. 3HCL in aq. THF and potassium carbonate at room temp. to give II. About 50 I were prepd., having antiulcer activity as shown by tests on rats.
