Reaction Steps
To a solution of 100 mg (0.236 mmol) of 1-(3-hydroxy-benzyl)-4-(4-isopropyl-phenyl)-6-prop-2-ynyloxy-1H-quinazolin-2-one in anhydrous DMF (5 mL) is added NaH (11 mg, 0.471 mmol) and the solution is allowed to stir until evolution of gas ceases. 1-bromo-2-(2-methoxyethoxy)-ethane (34 μl, 0.247 mmol) is added and the mixture is heated for 20 hours at 60° C. After cooling to room temperature, the reaction mixture is quenched with water and extracted with dichloromethane (2×20 ml). The combined organic layers are washed with brine, dried (Na2SO4), filtered and evaporated in vacuo to provide a yellow solid which is purified by flash chromatography on silica gel using petroleum ether/ethyl acetate (1:1) to provide the title compound as a yellow oil. Yield: 111 mg (85%).
