91% | With tetrakis(triphenylphosphine) palladium(0); sodium carbonate; In 1,4-dioxane; water; at 100℃;Inert atmosphere; Sealed tube; | To a reaction flask containing a solution of ethyl 2-(4-(4,4,5,5-tetramethyl-l,3,2- dioxaborolan-2-yl)cyclohex-3-en-l-yl)acetate (5.93 g, 20.17 mmol) in Dioxane (120 mL) were added 4-bromo-2-fluoro-3-methylpyridine (3.72 g, 19.58 mmol), Water (40.0 mL) and Na2C03 (8.30 g, 78 mmol). After the mixture was degassed with Ar for 10 min, Pd(Ph3P)4 (1.131 g, 0.979 mmol) was added. The flask was sealed and the mixture was heated to 100 C over night. The reaction mixture was cooled down and diluted with EtOAc and water, plus sonication to break up solids, then transferred to a separation funnel. The layers were separated and the aqueous layer was extracted once more with EtOAc. The organic layers were combined, washed with brine, dried over anhyd Na2S04, filtered and concentrated in vacuo to afford a white precipitate in a pale gold residue. The extract was purified via silica gel flash column chromatography, eluting with 0-25% ethyl acetate in hexane to give (0534) Intermediate 27B (gold pale oil, 5.01 g, 17.72 mmol, 91% yield). LC-MS Anal. Calc'd for C16H20FNO2 277.15, found [M+H] 278.1. Tr = 1.02 min (Method A).
