Procedure
7-Bromo-2-[2-hydroxy-4-(3-piperidin-1-ylpropoxy)phenyl]-3-methylquinazolin-4(3H)-one (9.5 mg, 0.020 mmol) and potassium carbonate (8.3 mg, 0.06 mmol) were stirred in DMF (0.5 mL) at room temperature, and 2-fluoroethyl tosylate (6.6 mg, 0.03 mmol) was dropwise added thereto and stirred at room temperature for 3 hours. The reaction solution was diluted with ethyl acetate, washed with water and saturated saline water, and the organic layer was dried with magnesium sulfate. The solvent was evaporated off, and the residue was purified through silica gel thin-layer chromatography (chloroform/methanol=9/1) to obtain the intended compound (4.5 mg, 47%) as a milky white solid.
