1462-37-9, The chemical industry reduces the impact on the environment during synthesis 1462-37-9, name is ((2-Bromoethoxy)methyl)benzene, I believe this compound will play a more active role in future production and life.
step Bl – Ethyl phenylcyanoacetate (22, 18.3 mL, 0.1054 mol, Ar1 = Ph) was added dropwise to a suspension of NaH (4.85 g, 0.1213 mol, 60percent dispersion in oil) in DMF (200 mL) cooled to 0 C. The resulting mixture was stirred at 0 C for 30 min then benzyl 2-bromoethyl ether (20 mL, 0.1265 mmol) was added. The reaction mixture was then stirred at 60 C overnight, cooled to RT and partitioned between EtOAc and a saturated aqueous NH4Cl. The aqueous layer was thrice back- extracted with EtOAc. The combined organic extracts were dried (Na2SO4), filtered and evaporated. The residue was purified by Si?2 chromatography eluting with a EtOAc/hexane gradient (5 to 95percent EtOAc) to afford 20 g (60percent) of 24a.
The chemical industry reduces the impact on the environment during synthesis ((2-Bromoethoxy)methyl)benzene. I believe this compound will play a more active role in future production and life.
