반응 단계
When using the general procedure of Example 5, the 2-nitro-2'-hydroxy-5'-methylazobenzene was replaced by an equivalent amount of 2-nitro-2'-hydroxy-3',5'-di-tert-amylazobenzene and the sodium hydroxide was replaced by an equivalent amount of potassium hydroxide, the hydrogenation was run in an Amsco mineral spirits/water (40/60) medium containing 1% sorbitan monooleate, Span 80, wetting agent at a hydrogen pressure of 6 atmospheres for a total period of 8 hours. The above named product was obtained in an isolated yield of 71.9%.
