Reaction Steps
The above propionamide (18 g, 0.094 mol) is added in portions to a solution prepared by adding 24 ml of 30% hydrogen peroxide to 250 ml of water containing 6 g (0.15 mol) of sodium hydroxide. The mixture is stirred at 80° C. for five hours, cooled and acidified with acetic acid to give 12.7 g (70%) of 5-ethyl-1,3-dimethyl-1H-pyrazolo[4,3-d]pyrimidin-7-ol, mp 220°-222° C. from ethanol.
