Procedure
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-triazine-5-one (1a) 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 (33") thus obtained has a melting point of 167°C.
