Versuchsvorschrift

To a solution of ammonium acetate (4.62 g) in methanol (10 ml) was added 2-methoxycarbonylmethoxyiminopropanedinitrile (3.34 g) under stirring, which was continued for 2 hours at room temperature and allowed to stand overnight. To the reaction mixture was added isopropyl alcohol (15 ml) and stirred for 15 minutes. The resulting precipitate was collected by filtration, washed with isopropyl alcohol and dried to give 2-cyano-2-methoxycarbonylmethoxyiminoacetamidine acetate (3.4 g), which was recrystallized from methanol, mp. 157° to 158° C. (dec.).
