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 41860-64-4 as follows. HPLC of Formula: C6H3FINO2
To 4-fluoro-2-iodo-1-nitrobenzene (40.0 g, 150 mmol) in THF (200 mL) at -40 C. was added phenylmagnesium chloride (80.0 mL, 2M in THF, 161 mmol) dropwise. The reaction was stirred for 30 min followed by dropwise addition of CuCN.2LiCl (26.0 g, 150 mmol) in THF. The mixture was stirred an additional 30 min at which time allyl bromide (20.0 g, 161 mmol) was added. The reaction was stirred at -40 C. for 2 h followed by rt overnight. The reaction was quenched with saturated ammonium chloride and extracted with EtOAc. The organic layer was washed with brine, dried (MgSO4) and concentrated. Purification by flash chromatography provided the title compound of step B (11.0 g, 60.7 mmol, 42%). 1H NMR (400 MHz, CDCl3) delta ppm 3.70 (d, J=6.4 Hz, 2H), 5.08-5.71 (m, 2H), 6.87-6.02 (m, 1H), 7.01-7.11 (m, 2H), 7.95-8.05 (m, 1H).
According to the analysis of related databases, 41860-64-4, the application of this compound in the production field has become more and more popular.
