실험 절차
At 15°, 650 ml of ethanol was saturated with gaseous ammonia. Seventy-three and three-tenths grams of 2-cyano-3,3-bis(methylthio)propenenitrile were added portionwise during 10 minutes. The reaction mixture was heated to 78° during 15 minutes. The slurry was allowed to cool to ambient temperature, then cooled to 10°. The solid was collected by filtration and washed with cold ethanol to give, when dried, m.p. 228°-229° (Literature m.p. 229°-230°, R. Gompper and W. Topel, Ber. 95, 2871 (1902)).
