실험 절차

To a solution of 7.38 g of 1,2-diaminonaphthalene in 175 ml of ethanol was added 8.56 ml of triethyl orthoacetate and the reaction mixture heated to reflux for 3.5 hours. The solvent was removed in vacuo and the residue partitioned between chloroform and water. The organic phase was separated, dried over magnesium sulfate and concentrated to a dark oil, 9.0 g.
