Reaction Steps
53.25 g (0.25 mol) of dimethyl dichloromaleate were dissolved in 100 ml of dimethylformamide, and 48.16 g (0.625 mol) of ammonium acetate were added. The mixture was rapidly heated to 120° C. and stirred at 110° C. to 120° C. for one hour. The solvent was subsequently removed by distillation, the residue was taken up in methylene chloride, and the solution was washed with water. The methylene chloride was removed by distillation on an evaporator, and, after, recrystallization 40 g (83% yield) of dimethyl aminochloromaleate were obtained in the form of yellowish, cubic crystals (m.p. 96°-98° C.)
