実験手順

9-bromo-2-(3-hydroxypropyloxy)-5-(3-pyridylmethyl)-4H-pyrido[3,2,1-jk]carbazole-4-one (250 mg) obtained in Example 110 was suspended in methanol (200 ml) and to the suspension was added a solution of methanesulfonic acid (57 mg) in methanol (5 ml) at room temperature. The mixture was stirred for 30 minutes. The solvent was evaporated under reduced pressure, and the resulting crude crystals were washed with a small amount of methanol and ether in succession to obtain the title compound (270 mg, 89%).
