2 g of 2-amino-4-propylamino-6-chloropyrimidine 3-oxide, prepared according to the first two stages of the process of Example 1, are suspended in 20 ml of ethanol. 1.75 g of piperidine are added. The reaction mixture is refluxed for 19 hours. After it has returned to room temperature, 660 mg of potassium hydroxide are added as a solution in 10 ml of ethanol. After 1 hour's stirring the mixture is filtered on paper. The filtrates are evaporated to dryness.
