Reaktionsschritte

A mixture of 6-chloropyrimidin-4(3H)-one (50 mg, 0.383 mmol), 4-(2-hydroxy-2-methylpropoxy)-3-methoxyphenylboronic acid Part D of Procedure 4 (184 mg, 0.766 mmol), copper (II) acetate, monohydrate (84 mg, 0.421 mmol), and pyridine (1.5 mL, 19.15 mmol) in DCM (4 mL) was stirred at RT under the presence of air overnight (21 hours). Pyridine (0.5 mL) and MeOH (0.5 mL) were added and continued to stir for 2 hours. The reaction was diluted with DCM, washed with 1N HCl, sat NaHCO3, dried (Na2SO4), and concentrated to afford crude product. The crude was purified using ISCO flash chromatography (silica gel/hexanes-ethyl acetate 100:0 to 0:100 gradient) to afford the desired product 6-chloro-3-(4-(2-hydroxy-2-methylpropoxy)-3-methoxyphenyl)-pyrimidin-4(3H)-one 11A (57.4 mg, 0.177 mmol, 46% yield) as a light brown solid.
