13.1 g | [0478] A solution of 2-fluoro-3 -(4,4,5, 5-tetramethyl- 1,3 ,2-dioxaborolan-2-yl)aniline (26.0 g, 110 mmol), 1-bromo-2,4,5-trifluorobenzene (12.5 g, 60 mmol), and K2C03 (38 g, 275 mmol) in co-solvent of dioxane (250 mL) and water (63 mL) was degassed and refilled with argon twice. To this solution was added Pd(dppf)2C12 (8.04g) under an atmosphere of argon. The solution was refluxed for 15 h. The reaction mixture was cooled to rt and the volatiles were removed under reduced pressure. The remaining residue was purified by column chromatography. The desired product fractions were collected and concentrated, and then the HC1 salt S3 was made by treatment with HC1/MeOH to yield 13.1 g of S3. |
