90213-66-4, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 90213-66-4, name is 2,4-Dichloro-7H-pyrrolo[2,3-d]pyrimidine. This compound has unique chemical properties. The synthetic route is as follows.
1.0 g of 2,4-dichloro-7H-pyrrole [2,3-d]pyrimidine was dissolved in 50 mL of dichloromethane under ice bath. To the above mixed solution, 1.06 g of p-toluenesulfonyl chloride, 1.08 g of triethylamine, and 0.019 g of 4-dimethylaminopyridine were slowly added. The mixed solution was stirred at room temperature for 5 h. After the reaction was completed, 150 mL of dichloromethane was poured into the above solution, and the organic phase was washed three times with 100 mL of each of water, aqueous citric acid and brine; The organic phase was dried over anhydrous magnesium sulfate (MgSO4). Recrystallization from petroleum ether gave 1.6 g of white pure product. The yield was 89%.
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 90213-66-4, 2,4-Dichloro-7H-pyrrolo[2,3-d]pyrimidine.
