Reference of 5414-19-7, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 5414-19-7, name is 1-Bromo-2-(2-bromoethoxy)ethane belongs to ethers-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
To a stirred solution of 3-amino-l-brotaunoisoquinoline (444 mg, 2.00 mmol) in anhydrous dimethylformamide (10175 mL) was added sodium hydride (60%, unwashed, 96 mg, 2.4 mmol) in one portion. The mixture was stirred at 25 0C for 5 min before 2-bromoethyl ether (90%, 250 DL, 2.00 mmol) was added. The mixture was stirred at 25 0C for 5 h and at 75 0C for 72 h before it was cooled to 25 0C, quenched with saturated ammonium chloride solution and diluted with ethyl acetate. The organic layer was separated, washed with water and brine, dried with Na2SO4, filtered and concentrated. Purification of the residue on silica gel eluting with 0% to 70% ethyl acetate/hexanes afforded Cap-143, step a as a yellow solid (180 mg, 31%) . Rt = 1.75 min (Cond. -MS-Wl) ; 90% homogenity index; LCMS: Anal. CaIc. for [M+H] + C13H14BrN2O: 293.03; found: 293.04.
The synthetic route of 1-Bromo-2-(2-bromoethoxy)ethane has been constantly updated, and we look forward to future research findings.
