摘要:
Novel aromatic carboxylic amides of the general formula: ##STR1## wherein each of R.sub.1 and R.sub.2 is a hydrogen atom or an alkyl group having 1-4 carbon atoms, R.sub.3 and R.sub.4 are hydrogen atoms or together form another chemical bond, each X is a hydroxyl group, a halogen atom, an alkyl group having 1-4 carbon atoms and an alkoxy group containing 1-4 carbon atoms, and n is an integer of 1-3 with the proviso that when .[.Xs.]. .Iadd.X's .Iaddend.are alkyl or alkoxy groups, they may be connected together to form a ring, as well as pharmaceutically acceptable salts thereof.These compounds possess a strong antiallergenic action and are thus useful for treatment of asthma, hay fever, .[.anticaria.]. .Iadd.urticaria .Iaddend.and atopic dermatitis.The above aromatic carboxylic amides can be prepared by reacting a reactive functional derivative of the general formula: ##STR2## where R.sub.1, R.sub.2, R.sub.3, R.sub.4, X and n have the same meanings given above, with an aminobenzoic acid of the formula: ##STR3## and, if desired, converting the resulting amide into the corresponding salts.
摘要:
The present invention provides an improved method for producing a nuclear substituted cinnamoylanthranilic acid compound.Illustrative of the process is the reaction of 3-hydroxy-4-methoxybenzaldehyde with 2-carboxymalonanilic acid in an inert solvent medium in the presence of a molar excess of piperidine to provide a high purity intermediate salt precipitate, and the salt is treated with an acidic reagent to yeild N-(3-hydroxy-4-methoxycinnamoyl)anthranilic acid product.
摘要:
