Reference of 26032-72-4 ,Some common heterocyclic compound, 26032-72-4, molecular formula is C10H6Cl2N2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
2.3 g (10 mmol) of intermediate product (A), 7.5 g (22 mmol) of l-(4- (4,4,5,5-tetramethyl-l,3,2-dioxaborolan-2-yl)phenyl)isoquinoline (D), and 0.6 g (0.5 mmol) of tetrakis-(triphenylphosphine)palladium were suspended in a mixed solvent of 70 ml of tetrahydrofuran and 50 ml of toluene to provide a suspension. The suspension was added to a solution in which 5.7 g (41 mmol) of potassium carbonate was dissolved in 50 ml of water. The obtained mixture was heated and refluxed for 12 hours. After separating the reaction fluid into two layers, an organic layer thereof was washed with a saturated sodium chloride aqueous solution and dried with anhydrous sodium sulfate. <134> The organic solvent was disti Hated and removed under reduced pressure, and then the residue was recrystallized with toluene. The extracted crystal was separated by filtration and washed with toluene to obtain 3.9 g (yield- 68.0 %) of compound (10).<135> 1H NMR (300MHz, CDCl3) 8.94 (d,2H), 8.68 (d,2H), 8.52 (d,2H), 8.39(d,2H), 8.21 (d,2H), 8.16 (s,lH), 7.94 (m,6H), 7.72 (m,4H), 7.61 (m,5H); MS[M+1] 563.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,26032-72-4, its application will become more common.
