실험 절차

Tris(dibenzylideneacetone)dipalladium(0) (635 mg) was added to a mixture of methyl 5-bromo-6-(4-fluorophenyl)-2-isopropoxynicotinate (3.65 g), cyclopropylboronic acid (2.55 g), dicyclohexyl(2′,6′-dimethoxybiphenyl-2-yl)phosphine (610 mg), a 2 M aqueous sodium carbonate solution (14.9 mL), and toluene (25 mL), and the resultant mixture was stirred at 100° C. for 2 hours in an argon atmosphere. The reaction mixture was allowed to cool to room temperature and poured to water, followed by extraction with ethyl acetate. The obtained organic layer was washed with saturated saline and dried over anhydrous magnesium sulfate, and then, the solvent was distilled off under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane/ethyl acetate) to obtain the title compound (3.18 g).
