반응 단계
When in Example 1, the 2'-hydroxy-3',5'-di-tert-amyl-2-nitroazobenzene is replaced by an equivalent amount of 2'-hydroxy-3'-tert-butyl-5'-methyl-5-chloro-2-nitroazobenzene and the ratio of the moles of alkali to moles of o-nitroazobenzene intermediate is 0.848/1, the product 5-chloro-2-(2-hydroxy-3-tert-butyl-5-methylphenyl)-2H-benzotriazole is obtained.
