Reference of 61272-76-2, These common heterocyclic compound, 61272-76-2, name is 4-Fluoro-2-iodoaniline, 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.
V-Benzyl-2~iodo-5~methoxybenzamide (1.61 g, 4.38 mmol), 4-fluoror~2-iodoamline (867 mg, 3.66 mmol), copper (I) iodide (139 mg, 0.73 mmol), and potassium carbonate (1.26 g, 9.12 mmol) were taken up in anhydrous DMSO (24 mL) and the resulting reaction mixture and the resulting reaction mixture was first stirred at 80 C for 2 hours, followed by heating to 135 C for another 16 hours. After cooling to room temperature, the mixture was filtered over celite and concentrated. Tire residue was diluted with an excess of Et?0 and washed with water. The organic layer was dried over Na2S04, filtered and concentrated. The residue was purified by flash column chromatography (EtOAc : Hex = 0: 100 to 100:0; then EtOAc : DCM = 0: 100 to 25:75) to give l0-Benzyl-8-fuoro-2-methoxy-5,10-dihydro-l IH- dibenzo[6,ej[1 ,4]diazepin~ l~one (565 mg, 44%) as a light yellow foam.
Statistics shows that 4-Fluoro-2-iodoaniline is playing an increasingly important role. we look forward to future research findings about 61272-76-2.
