Studies of Azoles and Azines. CI. Reaction of 4,6-Dihydroxypyrimidine and Barbituric Acid with 4,6-Dihydroxypyrimidine-5-carbaldehyde

Reaction of barbituric acid with 4,6-dihydroxypyrimidine-5-carbaldehyde in water at 20-60°C yields 5-(4,6-dihydroxypyrimidin-5-ylmethylene)barbituric acid. The same reaction performed in acetic acid at 120°C yields 5-aminomethylenebarbituric acid. One of the pyrimidine rings also opens in the reaction of 4,6-dihydroxypyrimidine with 4,6-dihydroxypyrimidine-5-carbaldehyde, which yields pyrano[2,3-d]pyrimidine-6-carboxamide derivatives.
