Abstract
Novel compounds which are 2,6-di-t-butylphenols substituted on the 4 position by an anilino group, which anilino group is substituted by a carboxyl substituent, a tetrazolyl substituent or an N-methyltetrazolyl substituent, are useful antiallergic agents. Pharmaceutical compositions containing and pharmacological methods of using such compounds are also disclosed, as are synthetic intermediates for preparing such compounds. Certain of the synthetic intermediates also exhibit useful antiallergic activity.
