In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 49845-33-2, name is 2,4-Dichloro-5-nitropyrimidine, the common compound, a new synthetic route is introduced below. category: pyrimidines
Aqueous ammonia(8.0ml) and N,N-diisopropylethylamine(13.2ml) were dissolved into 150ml dichloromethane. The mixture was added dropwise to a solution of 2,4-dichloro-5-nitropyrimidine(10.0g) in dichloromethane(30ml) at 0C. After the completion of the dropwise addition, the mixture was kept at the same temperature to react for 1 hour. The precipitate was filtered off. The filter cake was recrystallized to obtain a yellow solid(8.1g) in a yield of 90.1%. 1H NMR(400 MHz, DMSO-d6): delta 9.20(s, 1H), 9.02(s, 1H), 8.60(s, 1H)ppm.
The synthetic route of 49845-33-2 has been constantly updated, and we look forward to future research findings.
