4.76 g (20.0 mmol) of 2,4,5,6-tetraaminopyrimidine sulfate was added in small portions to a solution of 3.36 g (40.0 mmol) sodium bicarbonate in 100 mL of water with vigorous stirring. A brisk evolution of CO2 gas was observed. The resulting suspension was heated to 80° C. and 4.84 g (20.0 mmol) of 3,3′-dihydroxybenzil was added to the mixture. The reaction mixture was refluxed for 3 hours, at which point a bright-yellow precipitate was formed in abundance.
