Abstract

PURPOSE: The reaction between an oxobenzopyran amino formyl derivative and a cyanoacetyl halide is conducted in the presence of a substituted formamide to produce 1-azaxanthone derivative having antiallergic activity.
CONSTITUTION: An amino formyl derivative of formula I (ring A may be substituted) is reacted with a cyanoacetyl halide in the presence of a substituted formamide as dimethylformamide to form a 3-cyano-1-azaxanthone derivative. Then the hydrolysis of the product is effected using an acid as hydrochloric or sulfuric aicd to produce 1-azaxanthone-3-carboxylic acid derivative of formula III.
