Related Products of 1097871-23-2,Some common heterocyclic compound, 1097871-23-2, name is 1-Chloro-2,5-difluoro-4-iodobenzene, molecular formula is C6H2ClF2I, 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.
Step 2: Preparation of (S)-N-(-(4-chloro-2,5-difluorophenyl)(oxetan-3-yl)methyl)-2-methylpropane-2-sulfinamide To an oven-dried 500 mL round bottom flask under a nitrogen atmosphere was added 1-chloro-2,5-difluoro-4-iodobenzene (9.93 g, 36.18 mmol) in 175 mL anhydrous THF. The resulting solution was cooled to -100 C. with a diethyl ether/liquid nitrogen bath, and then n-BuLi solution (1.6M in THF, 22.6 mL, 36.2 mmol) was added dropwise so that the internal temperature remained between -90 and -100 C. The resulting yellow colored mixture was stirred between -90 and -100 C for 30 min and then (S,E)-2-methyl-N-(oxetan-3-ylmethylene)propane-2-sulfinamide (7.53 g, 39.80 mmol) in 15 mL THF was added dropwise via syringe so that the internal temperature remained between -90 and -100 C. The resulting mixture was stirred between -90 and -100 C. for 30 min and then quenched at the same temperature by dropwise addition of saturated NH4Cl solution followed by warming to room temperature. The mixture was diluted with 150 mL water and 150 mL EtOAc. The layers were shaken and separated and the organic phase was washed with saturated NaCl solution, dried over Na2SO4, and concentrated to a viscous nearly colorless oil which was purified by MPLC using silica gel (0-100% ethyl acetate/hexanes) to provide the desired single diastereomer (6.88 g, 20.38 mmol) as a white foam.

The synthetic route of 1097871-23-2 has been constantly updated, and we look forward to future research findings.
