반응 단계
When in Example 1, the 2'-hydroxy-3',5'-di-tert-amyl-2-nitroazobenzene was replaced by an equivalent amount of 2'-hydroxy-5'-tert-octyl-2-nitroazobenzene and the moles of sodium hydroxide per mole of o-nitroazobenzene intermediate was increased from 0.42/1 to 1.2/1, the product 2-(2-hydroxy-5-tert-octylphenyl)-2H-benzotriazole was obtained in an isolated yield of 62.6% of theory with a melting point of 104°-107° C. The mother liquor contained a compound believed to be an isomer of the desired product.
