Reaction Steps
A mixture of 125 grams of water, 26 ml. of 37% aqueous formaldehyde solution, 25 grams of maleimide, and 0.1 gram of anhydrous potassium carbonate was heated at its reflux temperature for 90 minutes, cooled to ambient temperature, and filtered. After removal of the water by heating under vacuum, there was obtained 32 grams of N-hydroxymethylmaleimide.
