Reaction Steps

A mixture of 300 mg (0.5 mmol) of 5-(4-aminobenzoyl)-5,6-dihydrophenanthridine and 230 mg of (0.55 mmol) of 2,6-dichlorobenzoyl chloride in 1.2 ml of pyridine is heated (100° C.) for 3 hr and then stirred at room temperature for 6 days. To the mixture is added 10 mg of 4-(dimethylamino)pyridine and the mixture stirred for 22 days. To the mixture is added 6 ml of 2N HCl and the solid filtered and washed with 2N HCl, 1N NaOH, H2O to give 0.57 g of solid. The solid is chromatographed on thick layer silica gel plates with hexane ethyl-acetate (1:1) to give 110 mg of solid. Recrystallization from CH2Cl2 -diisopropyl ether to give 73 mg of white crystals, m.p. 230°-235° C. Anal. Calc'd for C27H18Cl2 N2O2H2O: C,66.0; H,4.1; N,5.7; Cl,14.4. Found: C,65.5; H,4.1; N,5.6; Cl,14.6.
