摘 要:以丙二酸二乙酯和硫脲為原料,經(jīng)縮合,硫酸二甲酯甲基化兩步反應合成了2-甲硫基-3-甲基-6-甲氧基嘧啶-4-酮。該路線(xiàn)使用硫酸二甲酯替換文獻路線(xiàn)中的碘甲烷,并且將分步甲基化過(guò)程簡(jiǎn)化為一步甲基化,路線(xiàn)總收率達79.31%,提高了30%。通過(guò)熔點(diǎn)、MS、1H NMR確證目標化合物的結構。該路線(xiàn)原料易得,收率高,成本低,操作過(guò)程簡(jiǎn)便,具有放大前景。 |

Abstract:2-Methylthio-3-methyl-6-methoxypyrimidine-4-one was synthesized through two reactions including condensation and methylation using dimethyl malonate and thiourea as starting materials. The total yield was up to 79.31%. The structures of target compound were confirmed using MS and 1H NMR. The advantages of this method included commercialized raw materials, high yield, low cost, simple process, and easy industrialization. |
Key words:2-methylthio-3-methyl-6-methoxypyrimidine-4-one; herbicide intermediate; synthesis |
