Reaction Steps

A mixture of the product from Example 1E (0.1020 g, 0.41 mmol), 2,4-dimethoxypyrimidin-5-yl-boronic acid (0.0920 g, 0.50 mmol), dichlorobis (triphenylphosphine)-palladium (II) (0.0096 g, 0.014 mmol), and K3PO4.H2O in isopropyl alcohol (5 mL) and H2O (2 mL) was stirred at 65° C. for 2 hours. The reaction mixture was cooled to room temperature then concentrated under reduced pressure. The residue was partitioned between brine and ethyl acetate. The aqueous layer was washed with ethyl acetate, and the combined organic extracts were dried (MgSO4), and filtered. The filtrate was concentrated under reduced pressure and the residue was purified by column chromatography (7:3 hexane/ethyl acetate). Fractions containing product were combined to provide (0.0376 g, 30% yield). 1H NMR (CDCl3, 300 MHz), δ 8.37 (s, 1H), 7.95 (s, 1H), 7.86-7.82 (d, J=6 Hz, 2H), 7.71 (s, 1H), 7.64-7.59 (d, J=9 Hz, 1H), 7.46-7.6 (s, J=9 Hz, 1H), 4.08 (s, 3H), 4.06 (s, 3H), 3.89-3.84 (t, J=7.5 Hz, 2H), 3.30-2.98 (t, J=7.5 Hz, 2H). MS (DCl—NH3) [M+H]+ at 311.
