YieldReaction ConditionsOperation in experiment
With sodium hydroxide; water; In diethyl ether; Boron trifluoride etherate (0.453 ml, 3.89 mmol) and trimethyl borate (0.867 ml, 7.77 mmol) were stirred in anhydrous tetrahydrofuran (THF, 10 ml) for 10 minutes to form dimethoxyfluoroborane in situ.To a solution of the 4-fluoro(trifluoromethoxy)benzene (2.0 g, 11.1 mmol) in dry THF (30 ml) at -780C, was added ethylenediaminetetraacetic acid (EDTA, 1.36 g, 11.7 mmol) followed by a 1.4 M solution of sec-butyllithium in cyclohexane (8.33 ml, 11.7 mmol) and the reaction stirred for 2 hours under nitrogen. To this reaction mixture at - 780C, was then added dropwise the preformed dimethoxyfluoroborane mixture. The reaction was stirred at -780C for 30 minutes, warmed to room temperature for 30 minutes, and then quenched with water (10 ml). The volume of the reaction mixture was reduced in vacuo, then the residue dissolved in diethyl ether (10 ml) and washed with an aqueous solution of 10percent NaOH (50 ml). The aqueous layer was acidified and extracted with ethyl acetate (3 x 40 ml). The combined ethyl acetate extracts were dried over MgSO4 and concentrated in vacuo to afford the title compound as a single regioisomer (1.51 g).LCMS Rt = 1.38 minMS m/z 223 [M]-

250 mg With bis-triphenylphosphine-palladium(II) chloride; sodium carbonate; In 1,2-dimethoxyethane; water; at 100℃; for 3.0h;Inert atmosphere; A 100 mL screw cap bottle was charged with 2,4-dichloro-5-isopropenyl-pyridine (800 mg, 4.26 mmol [4-fluoro-3-(trifluoromethoxy)phenyl]boronic acid (606 mg, 3.1 mmol) and sodium carbonate (1.3 g, 12.8 mmol) in a mixture of DME (5 mL) and water (2.5 mL) and degassed with nitrogen for 15 min. Then Pd(PPh3)2.Cl2 (147 mg, 0.21 mmol) and again degassed with nitrogen for another 10 min. The resulting mixture was heated at 100 C for 3h. The reaction was monitored by LCMS. Then the reaction mixture was passed through a celite bed, diluted with water (25 mL) and extracted with EtOAc (2x50 mL). The combined organic layer was dried over anhydrous sodium sulfate and concentrated under reduced pressure to obtain the product, which was purified by chromatography to obtain 4-chloro-2-[2-fluoro-5- (trifluoromethoxy)phenyl]-5-isopropenyl-pyridine (250 mg) as an oil.
