Reaction Steps

0.1 mol of imidazolidine-2,4-dione, 3 ml of glacial acetic acid, 0.12 mol of pyridine-3-carbaldehyde and 30 ml of toluene were introduced into a round-bottomed flask. 5 ml of piperidine were also added to this mixture. The combination was heated at reflux for 17 h. After cooling, isopropanol was added. The precipitate obtained was filtered off and washed with isopropanol. The yield of 5-(3-pyridylmethylene)imidazolidine-2,4-dione was 85%.
