Synthetic Route of 51628-12-7,Some common heterocyclic compound, 51628-12-7, name is 2-(4-Iodophenyl)acetonitrile, molecular formula is C8H6IN, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
A solution of the nitrile (50.0 g, 206 mmol) in toluene (500 mL) was cooled to -25 0C, then Ti(O1Pr)4 (60.3 mL, 206 mmol) was added. A commercial (Aldrich) solution of EtMgBr (3.0 M, 137 mL, 411 mmol) was then added dropwise at a rate which maintained the internal temperature between -20 and -25 0C (over approximately 60 minutes). The mixture was stirred for 60 minutes at this temperature, then the BF3OEt2 (52.1 mL, 411 mmol) was added dropwise maintaining a constant internal temperature (over approximately 30 minutes). After stirring the resulting solution for 60 minutes, the mixture was poured into 750 mL 3 N HCl(aq) and stirred rapidly for 30 minutes while warming to room temperature. The mixture was then transferred to a separatory funnel, and allowed to settle for 30 minutes. The thick yellow oil which separated on the bottom was carefully removed, then dissolved in CH2Cl2 (1 L), dried (Na2SO4) and concentrated in vacuo to provide 24 g of the amine salt (RE2a) of sufficient purity (approximately 80%) to be used directly.
The synthetic route of 51628-12-7 has been constantly updated, and we look forward to future research findings.
