Paragraph 0037; 0041; 0043-0044, (2021/02/10)
The invention belongs to the technical field of compound synthesis, and particularly discloses a synthesis method of a 2, 4-dihalogen-6-aryl substituted triazine derivative. The synthesis method comprises the following steps: generating an intermediate triazine diketone compound from an aryl formate compound and biuret under the action of alkali, and reacting under the action of a halogenating reagent to obtain the 2, 4-dihalogen-6-aryl substituted triazine derivative. The method has the characteristics of cheap and accessible raw materials, can greatly lower the production cost, has the advantages of mild reaction conditions, single reaction product, fewer byproducts and no impurity removal difficulty, is simple in technological operation, can easily obtain the high-purity product, and issuitable for large-scale industrial production.

(Chemical Equation Presented) N-t-Butylamidines 1 on heating with diphenyl carbonate (2) at 150-180° gave the 1,3,5-triazine-2,4(1H,3H)-dione derivatives 5. Acylation of amidines 1 and cyclocondensation of the resulting carbamates 3 gave [1,3,5,7]tetrazocine-2,6-dione derivatives 4, and subsequent retro-ene reaction and ring contraction afforded triazine derivatives 5.

Reaction of 6-phenyl-4-thioxo-1,3,5-triazine-2-one with alkyl halide in the presence of 1 equiv. of sodium hydroxide resulted in 4-alkylthio-6-phenyl-1,3,5-triazine-2-one in good yield, whereas the above reaction provided 2-alkoxyl-4-alkylthio-6-phenyl-1,3,5-triazine in the presence of 2 equiv. of sodium hydroxide. 6-Phenyl-4-thioxo-1,3,5-triazine-2-one was oxidized with hydrogen peroxide to give 6-phenyl-1,3,5-triazine-2,4-dione. Further treatment with ethyl bromoacetate or (substituted) benzyl bromides yielded 2,4-dialkoxy-6-phenyl-1,3,5-triazines. At the same time, a small amount of 2-dimethylamino-4-alkoxy-6-phenyl-1,3,5-triazine were isolated. Preliminary bioassays indicate that the title compounds possess good activities against tobacco mosaic virus.

N-t-Butylbenzamidines 1 reacted with diphenyl phenylmalonate or diphenyl methylmalonate to give 6-hydroxypyrimidin-4(3H)-ones 4 or 5. Amidines 1 on reaction with diphenyl imidodicarboxylate afforded 1,3,5-triazine-2,4(1H,3H)- diones 8.
