Synthetic Route of 96797-15-8,Some common heterocyclic compound, 96797-15-8, name is 4-Iodo-1-trityl-1H-imidazole, molecular formula is C22H17IN2, 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.
A suspensionof 4 (3.0 g, 6.9 mmol), the appropriate 2-formyl boronic acid(1.6 g, 10.7 mmol) and K3PO4 (4.4 g, 20.8 mmol) in DMF (30 mL) andwater (6 mL) was purged with nitrogen for 5 min, followed by theaddition of Pd(PPh3)4 (0.6 g, 0.5 mmol) and the mixturewas purgedwith nitrogen for another 5 min. The reaction mixture was stirredat 90 C for 16 h under an atmosphere of N2. The solution wasallowed to cool and was filtered through a plug of celite. Themixture was diluted with water (50 mL) and was extracted withethyl acetate to afford the crude product which was purified byflash column chromatography on silica gel to yield 6 as a white solid(1.9 g, 66.7%). Mp 147e149 C. 1H NMR (300 MHz, Chloroform-d)d(ppm) 7.97 (dd, J 7.8, 1.4 Hz, 1H), 7.72e7.54 (m, 3H), 7.38 (h,J 3.2 Hz,11H), 7.25e7.19 (m, 6H), 7.07 (d, J 1.3 Hz, 1H). MS (EI) m/z 415.2 [MH].
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 4-Iodo-1-trityl-1H-imidazole, its application will become more common.
