Application 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-1-bromoisoquinoline (444 mg, 2.00 mmol) in anhydrous dimethylformamide (10 mL) was added sodium hydride (60%, unwashed, 96 mg, 2.4 mmol) in one portion. The mixture was stirred at 25 C. for 5 min before 2-bromoethyl ether (90%, 250 muL, 2.00 mmol) was added. This mixture was stirred further at 25 C. for 5 h and at 75 C. for 72 h before it was cooled to 25 C., quenched with saturated ammonium chloride solution and diluted with ethyl acetate. The organic layer was separated, washed with water and brine, dried over Na2SO4, filtered and concentrated. Purification of the residue on silica gel (gradient elution with 0% to 70% ethyl acetate in hexanes) afforded Cap-143, step a (180 mg, 31%) as a yellow solid. Rt=1.75 min (Cond.-MS-W1); 90% homogenity index; LCMS: Anal. Calc. 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.
