実験手順
Using the method of Example 1, 4-aminobenzylcyanide was reacted with 2,6-di-tertiary-butyl-p-benzoquinone to give 2,6-di-tertiary-butyl-4-(4'-cyanomethylphenylimino)-2,5-cyclohexadiene-1-one, m.p. 126.5°-127.5° C. Following the reduction method of Example 1, Step B, the corresponding anilino phenylacetonitrile, m.p. 146°-147° C., was obtained. This was converted to 5-[4-(3,5-di-t-butyl-4-hydroxyanilino)benzyl]tetrazole, m.p. 212°-214° C. (dec), following the method of Example 30, but carried out at 110° C. for 48 hours.
