実験手順

To a solution of 3-chloro-4-hydroxy-2′-(2-(2-hydroxypropan-2-yl)pyrimidin-4-yl)-5′,6-dimethyl-2H-[1,4′-bipyridin]-2-one (386 mg, 1.0 mmol) in N,N-dimethylformamide (1.7 mL) was added 1-(bromomethyl)-2,4-difluoro-3-methylbenzene (243 mg, 1.1 mmol), potassium carbonate (0.35 g, 2.52 mmol) and 18-crown-6 (7 mg). The slurry was stirred at ambient temperature for 18 hours. The reaction was partitioned between ethyl acetate and water. The organic layer was washed with water and brine and dried over magnesium sulfate. The solution was concentrated in vacuo to provide a brown oil. Normal phase chromatography (ethyl acetate/heptane) provided 319 mg of the alkylated product: MS (M+H) 528.
