Abstract

NEW MATERIAL:An anthranilic acid derivative of formula I:(X is halogen; R1 is H or lower alkyl group; R2 is benzoyl or cinnamoyl group which may be substituted by 1 to 3 methoxy groups at any positions).
EXAMPLE: N-(3,4,5-Trimethoxybenzoyl)-5-chloroanthranilic acid.
USE: Antiallergic drugs having a large activity and little side effects, effective by oral administration.
PROCESS: An anthranilic acid derivative of formula II is reacted with a reactive derivative of benzoic acid expressed by formula III, or a benzoxazine derivative of formula IV is hydrolyzed to give the objective compound of formula I.
