Versuchsvorschrift

When in Example 1, the 2'-hydroxy-3',5'-di-tert-amyl-2-nitroazobenzene was replaced by an equivalent amount of 2'-hydroxy-3'-methyl-5'-tert-butyl-2-nitroazobenzene, the product 2-(2-hydroxy-3-methyl-5-tert-butylphenyl)-2H-benzotriazole was obtained after a reaction time of 5 hours in an isolated yield of 81% of theory with a melting point of 145°-146° C.
