Procedure

9-bromo-5,6-dihydro-2-methoxy-4H-pyrido[3,2,1-jk]carbazole-4-one (300 mg) obtained in Example 101, step 6 was suspended in ethanol (17 ml), and pyrimidine-5-carboxyaldehyde (157 mg) prepared by the procedure described in Syn. Commun. 24, 253 (1994) and sodium hydroxide (291 mg) dissolved in water (1.7 ml) were added to the suspension at room temperature. The mixture was stirred at room temperature for 12 hours, and approximately half of the solvent was evaporated under reduced pressure. The crystals precipitated were recovered by filtration, and the residue was purified by alumina flash column chromatography (eluent: methylene chloride containing 4% methanol) to obtain the title compound (300 mg, 79%).
