Procedure

Methoxymethyl chloride (410 μL) was added to a suspension of potassium carbonate (1.24 g) in a solution of 5-bromo-8-hydroxy-6-methyl-1H-quinolin-2-one (480 mg) in dimethylformamide (9 mL) at 0° C. The reaction mixture is stirred for 18 hours at room temperature, filtered, the solvent removed in vacuo, and the product purified by flash column chromatography on silica gel, eluting with 2% methanol in dichloromethane.
