Procedure

4.1 g of 6-amino-4-methyl-3-methylsulfinyl-1,2,4-triazin-5-one are suspended in 50 ml of absolute methanol, and 4.3 ml of 30% strength methanolic sodium methylate solution are added at room temperature. The reaction proceeds slightly exothermically and the temperature rises to 35° C. The solution is then stirred at 50° C. for 30 minutes, whereupon a colourless precipitate separates out of the clear yellow solution. The reaction mixture is evaporated and the residue is taken up in ethyl acetate and ice-water. The organic phase is separated off, dried with magnesium sulfate and evaporated. The residue is washed with a little methanol and dried. 1.6 g of 6-amino-4-methyl-3-methoxy-1,2,4-triazin-5-one with a melting point of 198°-199° C. are obtained in this manner.
