Compound 531 (120 mg, 0.300 mmol) was dissolved in THF (2 mL), and a 2 mol/L solution of dimethylamine in THF (0.054 mL, 1.80 mmol) was added thereto, followed by stirring at room temperature for 4.5 hours. The reaction mixture was concentrated under reduced pressure, and the resulting residue was purified through silica gel column chromatography (chloroform), followed by reslurrying with a mixed solvent of 2-propanol and diethyl ether to afford the entitled Compound 533 (64.1 mg, 10%).
