In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 156150-67-3 as follows. Quality Control of 2-Chloro-1-fluoro-4-iodobenzene

To the stannane (0.39 g, 0.95 mmol) in DMF (10 ml) was added the 2-chloro-4-fluoroiodobenzene (0.73 g, 2.86 mmol), Cul (0.19 g, 1.05 mmol) and tetrakis(triphenylphosphine)palladium (0) (0.11 g, 0.095 mmol). The reaction was stirred at RT under N2 for 21 h. The reaction mixture was added to Et2O and the heterogeneous solution filtered through a bed of celite, washing with EtOAc. The filtrate was washed with water and brine and dried (MgSO4). Filtration and evaporation of the solvent in vacuo afforded a residue that was preadsorbed on silica gel. Purification by silica gel chromatography (4% EtOAc/hexane) yielded the arylacrylate (0.19 g, 78%), which was used directly in the next step.
