Reaction Steps

2-(2,6-Dimethyl-pyridin-4-yl)-7-fluoro-5-(2-isopropoxy-ethoxy)-3H-quinazolin-4-one (22) (960 mg, 2.58 mmol) was taken up in anhydrous DMF (10 mL). Sodium methoxide (25% solution in methanol, 12.9 mmol) was added. After the addition, the reaction mixture was stirred at 60° C. for 72 hours. The reaction mixture was cooled to room temperature, and quenched with saturated solution of NH4Cl. The product was extracted with ethyl acetate (3×200 mL). The combined organic layer was washed with water, brine, dried over Na2SO4, and evaporated to give crude product. The crude compound was purified by preparative HPLC, to give the title compound 23 as a white solid.
