Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 71759-88-1, name is 5-Iodo-1-methyl-1H-imidazole, A new synthetic method of this compound is introduced below., Product Details of 71759-88-1
[1845] 5-Iodo-1 N-methylimidazole (455 mg, 2.18 mmol) was dissolved in 10 mL THF at room temperature. EtMgBr (2.4 mL, 1.0 M in THF) was added dropwise. After 30 mins, the reaction mixture was cooled to 0 C. 10 mL THF solution of CuCN (175 mg, 1.96 mmol) and LiCl (166 mg, 3.9 mmol) was then added. 10 mins later, Compound (782) from Step A above (989 mg, 1.96 mmol, in 10 mL THF) was added. The reaction was stirred overnight. Sat. NH4Cl solution was added to quench the reaction. The resulting emulsion was filtered through a sintered funnel and the filtrate was extracted with EtOAc twice. The organic layer was washed with NaHCO3 solution and brine, dried over magnesium sulfate, filtered and evaporated in vivo. The resulting crude material was chromatographed on a silica gel column (using 1:1 hexanes/EtOAc then 10:1 CH2Cl2/MeOH) to obtain 330 mg of the title product. MS M+1=506 The enantiomers were seperated on a chiral AD column.
The synthetic route of 71759-88-1 has been constantly updated, and we look forward to future research findings.
