Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 39513-26-3, name is 5-Bromo-1,3-dihydrobenzoimidazol-2-one, This compound has unique chemical properties. The synthetic route is as follows., Safety of 5-Bromo-1,3-dihydrobenzoimidazol-2-one
To a round-bottomed flask containing DMF (35 mL) was added 5-bromo-1 ,3-dihydro- benzimidazo-2one (5.Og, 23 mmo), and the resu[ting soution was purged with nitrogen for 15 minutes. To this soution were added successivey bis(pinacoato)diboron (7.2g, 28mmo), potassium acetate (6.9g, 70 mmo), and PdC2(dppf)0H2C2 (1 .7g, 2.4 mmd). After heating at 95 C for 16 h, the back mixture was coded to rt and di?uted with brine (50 mL) and EtOAc (75 mL). The resu[ting precipitate was removed by fiftration and washed with EtOAc. The fiftrate was transferred to a separatory funnd and the ayers separated. The organic ayer was washed with water (3 x 50 mL), dried (Na2SO4), fiftered andconcentrated in vacuo. Trituration of the crude residue with DOM provided the desired product as a white soid (2.5g, 41 % yied). MS (ES): masss cacd. for 013H17BN203, 260.1; m/zfound, 261.2 [M+H1. 1H NMR (400 MHz, DMSO.-d6) 310.76 (s, IH), 10.65 (s, IH), 7.29 (dd, J= 7,7, 1.0 Hz, IH), 7.18 (s, IH), 6.92 (d, J= 7.5 Hz, IH), 127 (5, 12H).
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 39513-26-3.
