Adding a certain compound to certain chemical reactions, such as: 16234-10-9, Thieno[3,2-d]pyrimidin-4(3H)-one, 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: 16234-10-9, blongs to pyrimidines compound. Recommanded Product: 16234-10-9
Thieno[3,2-d]pyrimidine-4(3H)-one (4.9 g) was dissolved in acetic acid (20 mL) and then brome (5 mL) was added thereto. In a sealed reactor, the reaction mixture was stirred at 120 C. for 10 hours. The reaction mixture was cooled to room temperature and distilled under reduced pressure to remove acetic acid. The resulting mixture was added to ice water and the resulting solid was filtered and then dried to obtain the title compound without further purification. 1H NMR (400 MHz, DMSO-d6) delta 12.75 (brs, 1H), 8.36 (s, 1H), 8.24 (s, 1H).
The synthetic route of 16234-10-9 has been constantly updated, and we look forward to future research findings.
