摘要： A method for producing alkylated cyanoacetylurea from an easily obtainable starting material An industrially available cyanoacetylurea and a carbonyl compound are reacted in a polar solvent under reducing conditions to alkylate cyanoacetylurea In addition, a reaction of cyanoacetylurea and acetone under reducing conditions affords isopropylation of cyanoacetylurea.
