反応手順
To a solution of 2-chloro-6-(2,4-difluorophenyl)isonicotinic acid (0.10 g, 0.37 mmol) in DMF (1.9 mL) and water (0.6 mL) were added (2-methylpyrimidin-5-yl)boronic acid (0.31 g, 2.23 mmol), palladium(II)acetate (12.5 mg, 0.06 mmol), 3,3′,3″-phosphinidynetris(benzenesulfonic acid) trisodium salt (95.0 mg, 0.17 mmol) and diisopropylamine (0.19 mL, 1.30 mmol). The mixture was heated to 80° C. After 2 h, the mixture was filtered and the filtrate was purified by reverse phase chromatography (C-18, 95% water/acetonitrile→25% water/acetonitrile with 0.1% trifluoroacetic acid). To the product fractions was added HCl (2.0 M in ether) and the mixture was concentrated to give the hydrochloride salt of the title compound. MS 328.1 (M+1).
