Reaction Steps

To a solution of 4-(3-aminophenyl)-1H-benzo[h]quinazolin-2-one (20 mg, 0.07 mmol) in pyridine (3 mL) was added benzenesulfonyl chloride (127 μL, 0.99 mmol), and stirred at 80° C. for 5 hours. After the solution was cooled to room temperature, the solvent was removed under reduced pressure. The residue was diluted with chloroform, washed with a saturated aqueous sodium bicarbonate solution and dried over anhydrous sodium sulfate. The solvent was removed under reduced pressure, the residue was purified by silica gel column chromatography (hexane/ethyl acetate=4/1), to give the titled compound as a yellow amorphous form (5 mg, yield 15%).
