実験手順

To a mixture of 5-bromo-1-(sec-butyl)-4-methoxy-2-oxo-1,2-dihydropyridine-3-carbonitrile obtained in Step B (130 mg), 1-methyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (114 mg), 2M aqueous sodium carbonate solution (1.37 mL) and 1,2-dimethoxyethane (2.5 mL) was added tetrakis(triphenylphosphine)palladium(0) (52.7 mg), and the mixture was stirred with microwave irradiation at 100° C. for 1 hr. The reaction mixture was diluted with water, and the mixture was extracted twice with ethyl acetate. The extracts were combined, washed with saturated brine, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (basic silica gel, ethyl acetate/hexane) to give the title compound (90 mg).
