2-((2-Nitrophenyl)azo)-4-(1,1,3,3-tetramethylbutyl)phenol → 2-(2-hydroxy-5-t-octylphenyl)benzotriazole-N-oxide

Participants

Reaction Steps

The same procedure as in Example 14 was repeated, except that 2-nitro-2'-hydroxy-5'-t-butylazobenzene 15.0 g was replaced by 2-nitro-2'-hydroxy-5'-t-octylazobenzene 17.7 g, thus producing 15.2 g of 2-(2'-hydroxy-5'-t-octylphenyl)benzotriazole-N-oxide having a melting point of 106.0° to 111.0° C. at the yield of 90.2%.
