Reaction Conditions

Reaction Steps

Two liter of acetonitrile was added to 510 g of sodium 3-decyloxy-2-naphthalenehydroxamate obtained above, and stirred for about 30 minutes at 60° C. Thereupon, evolution of carbon dioxide gas was confirmed. The reaction mixture was further stirred with heating for 1 hour. Then, the insoluble matter (3,3'-didecyloxy-2-2'-dinaphthylurea) was filtered out, and the filtrate was concentrated. The residue was dissolved in 1 liter of ethyl acetate, and washed 3 times with 500 ml of water. The organic layer was separated from the aqueous layer, dried with Glauber's salt, and then concentrated. Thus, 323 g of whitish orange 3-decyloxy-2-naphthylamine (Compound 1) was obtained in a 84% yield. The melting point of the product was 64°-65.5° C.
