実験手順
A 4N solution of hydrogen chloride in dioxane (0.54 mL; 2.15 mmol) was added to a stirred solution of 2-chloro-5-fluoro-4-(4-fluoro-2-methoxyphenyl)pyrimidine (553 mg; 2.15 mmol) and 3-bromo-5-[(methylsulfanyl)methyl]aniline (500 mg; 2.15 mmol) in 1-butanol (4.8 mL). The batch was stirred at 140° C. for 8 hours. After cooling the batch was diluted with ethyl acetate and washed with sodium bicarbonate and saturated aqueous sodium chloride solution. The organic phase was filtered using a Whatman filter and concentrated. The residue was purified by chromatography (hexane/ethyl acetate 4:1) to give the desired product (450 mg; 0.99 mmol).
