Reaction Steps

To a solution of 2.0 grams (0.087 mole) of sodium in 125 milliliters of liquid ammonia was added a solution of 3.67 grams (0.089 mole) of acetonitrile in 10 milliliters of diethyl ether over a period of about five minutes. The reaction mixture was then cooled in a dry ice-acetone bath and a solution of 10.0 grams (0.065 mole) of 2-cyanonaphthalene in a minimum of dry diethyl ether was rapidly added within about five minutes after completion of the acetonitrile addition. The reaction mixture was stirred for about one and one-half hours and the ammonia was then allowed to evaporate. Water was cautiously added to the reaction mixture under nitrogen and the resulting mixture was extracted with diethyl ether. The ether was separated and the residue recrystallized from a mixture of chloroform and hexane. There was obtained 2.8 grams (22% of theoretical) of β-amino-β-(2-naphthyl)acrylonitrile, melting point 85°-90°C. Analysis: -- Calculated for C13H10N2 (percent): C, 80.39; H, 5.19; N, 14.42. Found (percent): C, 80.08; H, 4.99; N, 14.06.
