Procedure

Substitution products of 3-hydroxy-1,2,4-triazin-5-ones, indirect method of preparation: 2.3 g sodium are added to 500 ml methanol whereby a sodium methylate solution is formed. 23.4g 3-methylthio-4-amino-6-phenyl-1,2,4-triazin-5-one and 6.5 ml methyl iodide are added. The mixture is boiled for one hour. When cooling down the mixture, a crystalline precipitate separates. The crystals are removed by suction and recrystallized from methanol and optionally once more from acetic acid ester. The 3-methoxy- 4-amino-6-phenyl-1,2,4-triazin-5-one thus obtained has a melting point of 165°C.
