HCID 76605Phenol, 2-(2H-benzotriazol-2-yl)-4-(1,1-dimethylethyl)-

Procedure

When in Example 13, the 2'-hydroxy-5'-methyl-2-nitroazobenzene was replaced by an equivalent amount of 2'-hydroxy-5'-tert-butyl-2-nitroazobenzene, the reduction reaction went rapidly to yield the product 2-(2-hydroxy-5-tert-butylphenyl)-2H-benzotriazole.
