実験手順
When in Example 1, the 2'-hydroxy-3',5'-di-tert-amyl-2-nitroazobenzene was replaced by an equivalent amount of 2'-hydroxy-5'-methyl-2-nitroazobenzene and the mole ratio of sodium hydroxide to o-nitroazobenzene intermediate was increased from 0.42/1 to 1.26/1, the reaction went rapidly to yield the product 2-(2-hydroxy-5-methylphenyl)-2H-benzotriazole.
