Procedure

To a solution of 2-chloro-8,9-dihydro-7-[(hydroxy)(5-methyl-1-trityl-1H-imidazol-4-yl)methyl]-10-methylpyrido[1,2-a]indol-6(7H)-one (1.64 g) in dichloromethane (32 ml) were added pyridine (0.83 ml) and acetic anhydride (0.53 ml). The solution was refluxed for 24 hours. After being cooled, the solution was washed with water twice and brine, dried over sodium sulfate, and evaporated, to give 7-[(acetoxy)(5-methyl-1-trityl-1H-imidazol-4-yl)methyl]-2-chloro-8,9-dihydro-10-methylpyrido[1,2-a]indol-6(7H)-one (1.49 g).
