Abstract

NEW MATERIAL:An aminophenyltetrazole derivative expressed by formula I (R1 is lower alkyl; R2 and R3 are H, lower alkyl, lower alkoxyl or halogen) and a salt thereof with a pharmaceutically suitable cation (Na+ or Ca2+).
EXAMPLE: 5-(3-Ethyloxalylaminophenyl)tetrazole.
USE: An antiallergic agent with low toxicity.
PROCESS: An aminophenyltetrazole compound containing a partially novel compound expressed by formula II, e.g. novel 5-(4-methyl-2-aminophenyl)tetrazole, is reacted with an oxalyl derivative expressed by formula III (A is halogen or lower alkoxyl) in a suitable solvent, if necessary in the presence of a base, to prepare the compound expressed by formula I.
