Procedure

To 0.193 g (1.2 mmol) of 3-methylthiophene-2-carbonyl chloride in 3 ml of dichloromethane, cooled to 0° C., is added 209 μl of triethylamine. The mixture is stirred and 0.30 g (1 mmol) of 5-(4-aminobenzoyl)-5,6-dihydrophenanthridine is added. The mixture is stirred at room temperature overnight and then concentrated under vacuum. To the residue is added 30 ml of ethyl acetate and the mixture washed with 2 ml each of water, 2N citric acid, LM sodium bicarbonate and brine. The organic layer is dried (Na2SO4) and the solvent removed to give 0.30 g of solid. The solid is chromatographed on thick layer silica gel plates with ethyl acetate-hexane (1:1) as solvent to give 150 mg of product as a yellow foam. Anal. Calc'd for C26H20N2 O2S: C,71.3; H,6.0; N,6.9; S,7.9. Found: C,71.0; H,5.8; N,6.8; S,7.8.
