Participants

Reaction Steps

120 parts of 2-cyano-3-methoxy-N-methylmaleimide are dissolved in 600 parts of methylglycol and 13.5 parts of ammonia are then passed into the ice-cooled solution. Stirring is then continued for 3 hours at room temperature, and the resulting precipitate is filtered off under suction, washed with methanol and then with water, and dried to give 90 parts (83% of theory) of 3-amino-2-cyano-N-methylmaleimide.
