Reaction Steps

To a suspension of methyl 12-cyclohexyl-4-trifluoromethanesulfonyloxy-6,7-dihydro-5-oxa-7a-azadibenzo[a,e]azulene-9-carboxylate (130 mg, 0.248 mmol), 3-(1,3,2-dioxaborinan-2-yl)pyridine (53 mg, 0.323 mmol) and sodium hydrogen carbonate (62 mg, 0.744 mmol) in 1,2-dimethoxyethane (2 ml) and water (0.75 ml) was added tetrakis(triphenylphosphine)palladium (16 mg, 0.014 mmol), and the mixture was heated at 90° C. for 3 hr. The reaction mixture was cooled to room temperature, saturated aqueous sodium hydrogen carbonate solution was added, and the mixture was extracted with ethyl acetate. The organic layer was successively washed with saturated sodium hydrogen carbonate solution and saturated brine, and dried over anhydrous magnesium sulfate. After filtration, the solvent was evaporated under reduced pressure and the residue was purified by silica gel column chromatography (hexane:ethyl acetate=1:2) to give methyl 12-cyclohexyl-4-(pyridin-3-yl)-6,7-dihydro-5-oxa-7a-azadibenzo[a,e]azulene-9-carboxylate (92 mg, yield 82%).
