Abstract

NEW MATERIAL:An aminophenyltetrazole derivative of formula I (R is 1W4C alkyl), and its salt with a pharmacologically acceptable cation.
EXAMPLE: 5-(2-Ethyloxalylaminophenyl)tetrazole.
USE: A low-toxic anti-allergic agent.
PROCESS: The compound of formula I is prepared by reacting 5-(2-aminophenyl) tetrazole of formula II (a novel compound) with an oxalyl derivative of formula III (A is halogen or 1W4C alkoxy; R is 1W4C alkyl) in a proper solvent, and if necessary, converting the product to a salt with a pharmacologically acceptable cation. The novel compound of formula II can be obtained by reducing 5-(2-nitrophenyl)tetrazole with hydrochloric acid and tin.
