Product 1

HCID 142973682-(2-hydroxy-5-t-octylphenyl)benzotriazole-N-oxideYield 90%

Procedure

The same procedure as in Example 1 was repeated, except that 2-nitro-2'-hydroxy-3',5'-di-t-amylazobenzene 25.5 g was replaced by 2-nitro-2'-hydroxy-5'-t-octylazobenzene 23.7 g, thus producing 20.3 g of 2-(2-hydroxy-5-t-octylphenyl)benzotriazole-N-oxide having a melting point of 106° to 110° C. at the yield of 90.0%.
