実験手順

Example 1 is repeated, except that an equivalent amount of 2-nitro-2'-hydroxy-3', 5'-di-tert.-butylazobenzene (91% pure) is used instead of 2-nitro-2'-hydroxy-5'-methylazobenzene and a mixture of 40 g of xylene and 60 g of diethylenetriamine instead of 80 g of xylene and 20 g of diethylenetriamine. The hydrogenation is carried out at 50° C. After work up of the hydrogenation solution, the product is crystallized from a mixture of 40 g of xylene and 160 g of methanol. The product (title compound) is isolated in a yield of 90% of theory. Melting point: 152°-154° C.
