Reaction Steps
To a solution of 8,9-dihydro-10-methyl-7-[(5-methyl-1-tosyl-1H-imidazol-4-yl)methylene]pyrido[1,2-a]indol-6(7H)-one (1.0 g) in the mixture of tetrahydrofuran (10 ml) and methanol (10 ml) was added 2N-sodium hydroxide. The mixture was heated at 80° C. for 5 hours. After being cooled, the reaction mixture was neutralized with acetic acid, and added water (40 ml). The precipitates were filtered to give 8,9-dihydro-10-methyl-7-[(5-methyl-1H-imidazol-4-yl)methylene]pyrido[1,2-a]indol-6(7H)-one (0.5 g).
