Reference of 698-00-0, 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. 698-00-0, name is 2-Bromo-N,N-dimethylaniline belongs to bromides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
A dry Schlenk tube under argon atmosphere was charged with the 2-bromo-N,Ndimethylaniline (1.99 g, 10 mmol) in degassed THF (15 mL). The solution was cooled at -78 C and n-BuLi (2,4 M in THF, 1.1 eq.) was added. The mixture was stirred for 30 min at -78 C and then, at 0 C for 15 minutes. Then PPh2Cl (1.93 mL, 10.5 mmol) neat was added at -78 C under an argon atmosphere. The white solution was filtered on a pad of celite, the solid was washed with pentane (20 mL), ether (20 mL) and CH2Cl2 (20 mL). 2-(diphenylphosphino)-N,N-dimethylaniline was obtained after purification by flash chromatography on silica gel (eluent : AcOEt / cyclohexane 10 / 90) as a white solid (1,67 g, 56%).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 2-Bromo-N,N-dimethylaniline, other downstream synthetic routes, hurry up and to see.
