実験手順

A mixture of 4-chloro-2-(3-chlorophenyl)-6-(trifluoromethyl)pyrimidine (0.076 g, 0.26 mmol), 4-chloro-1-(4-((4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)methyl)benzyl)-1H-pyrazole (0.129 g, 0.39 mmol), Pd(dppf)Cl2 (0.021 g, 0.03 mmol), and powdered Na2CO3 (0.082 g, 0.77 mmol) in dioxane (2 mL) and water (1 mL) was stirred under an argon atmosphere at 90° C. for 3 h. After this time, the mixture was cooled and filtered through celite with ethyl acetate washes. The filtrate was washed with brine (3×15 mL), dried over sodium sulfate, filtered, and concentrated. The residue was purified by column chromatography (silica, hexane/ethyl acetate) to afford the title compound (0.073 g, 98%) as an off-white solid. MW=463.28. 1H NMR (DMSO-d6, 300 MHz) δ 8.37-8.30 (m, 2H), 8.07 (s, 1H), 7.96 (s, 1H), 7.72-7.66 (m, 1H), 7.65-7.58 (m, 1H), 7.54 (s, 1H), 7.40 (d, J=8.1 Hz, 2H), 7.22 (d, J=8.1 Hz, 2H), 5.26 (s, 2H), 4.31 (s, 2H); APCI MS m/z 463 [M+H]+.
