75% | With (2,2,2-trifluoroethoxy)trimethylsilane; cesium fluoride; dichlorobis(trimethylphosphine)nickel In 1,4-dioxane at 100℃; for 12 h; Inert atmosphere; Sealed tube | Under an argon atmosphere,To the reaction vessel, 1.4 mg (0.005 mmol) of dichlorobis (trimethylphosphine) nickel,77.4 mg (0.5 mmol) of 4-chlorobenzamide,152 mg (1.0 mmol) of cesium fluoride,140 mg (0.55 mmol) of 4,4,5,5,4 ', 4', 5 ', 5'-octamethyl-2,2'-bi (1,3,2-dioxaborolanyl)180 mg (1.05 mmol) of trimethyl (2,2,2-trifluoroethoxy) silane and 0.5 mL of 1,4-dioxane were added and sealed,And the mixture was stirred at 100 ° C. for 12 hours.After the reaction vessel was cooled to room temperature, 1 mL of a saturated aqueous solution of ammonium chloride was added, and the mixture was extracted three times with 8 mL of ethyl acetate, and the obtained organic phases were combined.The solvent was distilled off under reduced pressure, and the residue was purified using silica gel column chromatography (hexane: chloroform: ethyl acetate = 4: 1: 0 to 4: 1: 1)92 mg (white solid, yield 75percent) of 4- (4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl) benzamide was obtained. |
