Adding a certain compound to certain chemical reactions, such as: 216393-67-8, name is 4-Chloro-2-fluoro-6-iodoaniline, belongs to iodides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 216393-67-8, HPLC of Formula: C6H4ClFIN
A mixture of Int-172-27 (5 g , 18.4 mmol), 23 (9.9 mL, 110.5 mmol), K2CO3 (3.05 g, 22.1 mmol), DPPP (366 mg, 0.92 mmol) and Pd(OAc)2 (41 mg, 0.18 mmol) in 60 mL H2O/toluene (9:1) was heated at 90oC for 24h. After the mixture was cooled to room temperature, concentrated HCl (14 mL) was slowly added and the mixture was stirred at room temperature for 1h. The product was extracted with EtOAc (3X). The organic phase was dried over anhydrous Na2SO4 and concentrated under reduced pressure. The product was purified by column chromatography using hexanes/EtOAc (0 to 20% EtOAc in hexanes) and obtained as a pale brown solid (1.3 g) in 37% yield. LCMS: (M+1) m/z = 188.
