実験手順

10-bromo-2-ethoxycarbonylmethyloxy-5-methyl-4H-pyrido [3,2,1-jk]carbazole-4-one (200 mg) obtained in Example 52 was suspended in a mixed solution of ethanol (10 ml) and methylene chloride (10 ml), and IN aqueous solution of sodium hydroxide (1 ml) was added to the suspension. The mixture was stirred at room temperature for 90 minutes, and the solvent was evaporated under reduced pressure. To the residue was added water and 1N hydrochloric acid to pH 1, and the crystals precipitated were recovered by filtration to obtain the title compound (170 mg, 91%).
