These common heterocyclic compound, 96797-15-8, name is 4-Iodo-1-trityl-1H-imidazole, 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. Product Details of 96797-15-8
Under nitrogen protection,Tetrakistriphenylphosphine palladium (2.0 g, 1.7 mmol, 0.074 eq), 4-iodo-1-trityl-1H-imidazole (0102-1) (10.0 g, 23.0 mmol, 1.0 eq),2-aldehyde phenylboronic acid (0103-1) (4.1 g, 27.5 mmol, 1.2 equiv) andTripotassium phosphate (12.0 g, 46 mmol, 2.0 equiv)Add to a mixture of 180 ml of dimethylformamide and water (5:1),Heat to 90C and react for 6 hours.Cool to room temperatureAfter suction filtration through Celite, the resulting filtrate was diluted with ethyl acetate to 1000 ml, washed with saturated brine three times, dried over anhydrous sodium sulfate, concentrated under reduced pressure, and purified by silica gel column chromatography (eluent: petroleum ether: ethyl acetate. Ester = 8:1 and petroleum ether: dichloromethane = 2:1),2-(1-trityl-1H-imidazol-4-yl)benzaldehyde (5.2 g, yield: 54%) was obtained as a white solid.
The synthetic route of 4-Iodo-1-trityl-1H-imidazole has been constantly updated, and we look forward to future research findings.
