Reaction Conditions

Reaction Steps

Benzoyl chloride is added to a solution of 2-(methoxyethoxymethyl)-7-aminoanthra[1,9cd]pyrazol-6-(2H)one and triethylamine in methylene chloride at 0° C. The mixture is stirred for 16 hours, quenched with water, and extracted with ethyl acetate (×2). The combined organic layer is washed with sodium bicarbonate solution, and brine, dried and evaporated. The crude reaction mixture is then taken in aqueous 6N hydrochloric acid, and heated at 80° C. for 4 hours. After cooling, the mixture is extracted with ethyl acetate (×2), washed with brine, dried, and evaporated. The reside is chromatographed on silica gel to furnish the desired amide as a yellow solid.
