Procedure

A solution containing 0.35 g (2.0 mmol) of 5-chloro-2,4-dimethoxypyrimidine and 0.35 g (7.0 mmol) of hydrazine hydrate in 2.9 g of methanol was heated at reflux with stirring for 8 hours. The mixture was then cooled causing a precipitate to form water was added until the precipitation appeared to be complete and the precipitate was then recovered by vacuum filtration and allowed to air dry overnight to obtain 0.23 g (66 percent of theory) of the title compound as a white solid. The product melted at 172°-173° C. after changing crystalline form from needles to cube-like shapes in a phenomenon that appeared to involve sublimation.
