Acrylonitrile → HCID 13061753, compound

Participants

Reaction Steps

915 g N-isopropyl-N-(3-methyl-1,3-butadienyl)-carbamic acid methyl ester are heated without a solvent to 120° C. and 345 g acrylonitrile added dropwise. After completion of the addition the mixture is stirred for 1 hour at 140°. The resulting 2-(N-isopropyl-N-carbomethoxyamino)-4-methyl-3-cyclohexene-nitrile is heated at 200° and treated over a period of 2 hours portionwise with 386 g powdered sulphur. The reaction mixture is then stirred for 2 hours at 205° C. The resulting mixture is distilled under high vacuum at 110°-120° (0,1 torr), recrystallisation of the residue from benzine fraction yields the title product m.p. 100°-101°.
