Reaction Steps

The same procedure as in Example 1 was repeated, except that n-butanol 80 g was replaced by n-propanol 80 g, and that 2-nitro-2'-hydroxy-3',5'-di-t-amylazobenzene 25.5 g was replaced by 2-nitro-2'-hydroxy-5-methylazobenzene 17.1 g, thus producing 14.1 g of 2-(2-hydroxy-5-methylphenyl)benzotriazole-N-oxide having a melting point of 138° to 140° C. at the yield of 88%.
