To a solution of the compound [4-5] obtained in the process (5) (497 mg) in N,N-dimethylformamide (10 mL) were added potassium carbonate (511 mg) and methyl iodide (0.12mL) at 0C, and then the reaction mixture was stirred at room temperature for 13 hours. The reaction mixture was quenched with water, and extracted with ethyl acetate. The obtained organic layer was dried over anhydrous sodium sulfate, filtered, and the filtrate was concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography to give the titled compound (512 mg) as a white solid. 1H-NMR (400MHz, CD3 OD) delta: 8.25-8.00 (1H,br), 7.59 (1H,d, J = 8.1 Hz), 7.33 (1H,d, J = 0.7 Hz), 7.19 (1H,t, J = 2.8 Hz), 7.04 (1H, dd, J = 8.1, 1.2 Hz), 6.53 (1H, s), 3.73 (2H, s), 3.69 (3H, s).
