Versuchsvorschrift
Under the same conditions as the method for synthesizing Compound A7-1, (3-bromo-6,6-dimethyl-11-oxo-6,11-dihydro-5H-benzo[b]carbazol-9-yl oxy)-acetic acid methyl ester was prepared from Compound JJ2 and hydroxy-acetic acid methyl ester. The resultant was dissolved in MeOH (0.35 ml), added with aqueous solution of sodium hydroxide (6 mol/1), and stirred at room temperature for 10 min. The reaction solution was added with hydrochloric acid (3 mol/1), extracted with diethyl ether and dried over anhydrous magnesium sulfate. After the concentration under reduced pressure, white solid was obtained, which was then washed with methylene chloride to obtain the title compound (11.2 mg, 48%).
