Compound 39 (391 mg, 1.00 mmol) was dissolved in NMP (10 mL), and 1-methylpiperazine (1.11 mL, 10.0 mmol) was added thereto, followed by stirring overnight at 150° C. The reaction mixture was poured into water, followed by extraction with ethyl acetate. The organic layer was washed with a saturated aqueous solution of sodium chloride and dried over anhydrous magnesium sulfate, and then the solvent was distilled away under reduced pressure. The resulting residue was purified through silica gel column chromatography (chloroform:methanol=19:1) to afford the entitled Compound 41 (22.2 mg, 5%).
