Adding a certain compound to certain chemical reactions, such as: 1119280-68-0, 2-Chlorothieno[3,2-d]pyrimidine, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, Recommanded Product: 2-Chlorothieno[3,2-d]pyrimidine, blongs to pyrimidines compound. Recommanded Product: 2-Chlorothieno[3,2-d]pyrimidine
2-chlorothieno[3,2-d]pyrimidine (4, 0.9 g, 5 mmol) was taken up in acetonitrile (10 mL) to form a mixture. Bromine (0.450 mL, 8 mmol), followed by HI04 (0.558 g, 2 mmol) were added to the mxiture and the mixture was refluxed for 2 h. Thin layer chromatography (TLC) of the reaction mixture showed complete conversion of compound 4 to compound 5. The reaction mixture was then cooled and poured in ethyl acetate to form a mixture. Water, followed by saturated sodium thiosulfate were added to the mixture to form a biphasic mixture having an organic layer and an aqueous layer. The organic layer was separated from the aqueous layer, washed sucessively with bicarbonate and brine, dried over Na2S04 and concentrated to obtain 7-bromo-2-chlorothieno[3,2-d]pyrimidine (5, l g, 68.96%). ‘HNMR (CDCl3): 9.18 (s, 1 H), 8.10 (s, 1 H).
The synthetic route of 1119280-68-0 has been constantly updated, and we look forward to future research findings.
