Versuchsvorschrift

A solution of 191.3 g of 3-chloro-2-cyano-4-methyl- 2-pentenenitrile in 300 ml of ethanol was added slowly, maintaining the temperature below 40°, during 1.3 hours, to a mixture of 800 ml of concentrated ammonium hydroxide and 1000 ml of ethanol. The mixture was stirred for 3 hours, then poured over 2000 ml of ice. The solid was collected, washed with water and dried to obtain 122.0 g of 3-amino-2-cyano-4-methyl-2-pentenenitrile, mp 186°-188°.
