YieldReaction ConditionsOperation in experiment
76% With bis(tri-t-butylphosphine)palladium(0); dicyclohexylmethylamine; lithium chloride; In 1,4-dioxane; at 110℃; for 16h;Inert atmosphere; General procedure: A flask containing LiCl (980 mg,23.1 mmol), 2-bromo-4-fluoroanisole (1.0 mL, 7.7 mmol), DCMA (1.8 mL,8.4 mmol) and <strong>[1001-26-9]ethyl 3-ethoxyacrylate</strong> (3.3 mL, 23 mmol) in 1,4-dioxane(20 mL) was degassed by passing a stream of nitrogen through the mixturefor 10 min. Bis(tri-t-butylphosphine) palladium(0) (166 mg, 0.32 mmol) wasadded, and reaction mixture was heated at reflux under nitrogen for 16 h. Thebrown mixture was then cooled and partitioned between ethyl acetate andwater. The layers were separated, and the organic layer was washedsequentially with aqueous NH4Cl and brine, followed by drying over Na2SO4.The mixture was filtered, and the filtrate was concentrated under reducedpressure to give an oil which was purified by flash chromatography on silica(40 g, 10?50percent ethyl acetate in heptane) to afford 22c as an orange oil (1.93 g,92percent) as an inseparable mixture of E- and Z-isomers: 1H NMR (CDCl3, 500 MHz)alkene protons d: 5.21, 5.33 ppm (1:1 ratio); LCMS (ES): 269.2 (MH). HRMSCalcd for C14H17FO: 269.1184. Found: 269.1196.
