Reaction Steps

A 20-mL sealed tube, with stirrer bar, was charged with 4-chloro-2-(3-chlorophenyl)-6-ethylpyrimidine (0.303 g, 1.20 mol), methyl 2-methyl-2-(4-((4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)methyl)phenyl)propanoate (0.420 g, 1.32 mmol), Pd(dppf)Cl2 (0.098 g, 0.12 mmol), and powdered Na2CO3 (0.380 g, 3.60 mmol). Dioxane (6 mL) and water (3 mL) were added. The resulting mixture was stirred under Ar at 90° C. for 2 h. After this time, the mixture was cooled to room temperature and filtered through celite washing with ethyl acetate until the filtrate was colorless. The filtrate was washed with saturated sodium chloride (3×25 mL) then dried over sodium sulfate, filtered, and concentrated under reduced pressure. The residue (0.87 g) was purified by chromatography on silica using hexane/dichloromethane (10:0 to 8:2) as eluent to afford the title compound (0.47 g, 96%) as a colorless oil. MW=408.92. 1H NMR (CDCl3, 300 MHz) δ 8.50-8.47 (m, 1H), 8.40-8.35 (m, 1H), 7.46-7.37 (m, 2H), 7.31-7.24 (m, 4H), 6.87 (s, 1H), 4.10 (s, 2H), 3.65 (s, 3H), 2.77 (q, J=7.8 Hz, 2H), 1.57 (s, 6H), 1.32 (t, J=7.5 Hz, 3H); ESI MS m/z 409 [M+H]+.
