Abstract
NEW MATERIAL:An 1-azaxanthone-3-carboxylic acid derivative of formula I: (R1 is alkoxy or monoalkylamino group; R2 is alkyl, alxoxy, halogen, nitro, OH, carboxy, -CH=CH-CH=CH- to form a benzene ring with the adjacent carbon atom, or amino group which may be substituted by at least one alkyl group, m is 0, 1, or 2).
EXAMPLE: 7-Methyl-2-methylamino-1-azaxanthone-3-carboxylic acid.
USE: Preventives and remedies for allergic diseases, e.g. allergic asthma, allergic dermatitis, hay fever, etc.
PROCESS: A compound of formula II is hydrolyzed in an organic solvent, e.g. formic acid or methanol, at 50W150°C under acidic conditions to give the objective 1- azaxanthone-3-carboxylic acid derivative of formula I.
