A 5-alkoxy -1, 2, 4-triazole [4,3-c] pyrimidin -3 (2H)-THIONES method for the preparation of

The invention relates to a preparation method of 5-alkoxy-1,2,4-triazole[4,5-c]pyrimidine-3(2H)-thioketone. The method comprises the following steps: dissolving 2-alkoxy-4-hydrazino-5(or 6)-halogenated pyrimidine into an organic solvent under protection of N2, adding a catalyst and carbon disulfide to be mixed, stirring for 0.5-3h, and raising the temperature to backflow; cooling after backflow reaction, acidizing and adjusting pH; carrying out suction filtration, recrystallizing solid in a recrystallization solvent, separating the solid, and carrying out vacuum drying. By utilizing the preparation method, the temperature is directly raised to backflow, an oxidizing agent of hydrogen peroxide is not used, the temperature of dropwise added hydrogen peroxide does not need to be controlled, and therefore, elemental sulfur can not be generated, the elemental sulfur does not need to be filtered to remove, the steps are simple, and the reaction is easy to control. The adopted catalyst has good catalytic performance, the reaction yield is greatly improved, the reaction condition is moderate, and special equipment is not needed.
