Conditions

Temperature: 100 °C

Procedure

To a solution of 2,7-bis(3,5-dimethylpiperidin-1-ylsulfonyl)-10-methylacridine-9(10H)-thione (290 mg, 0.5 mmole) in pyridine (5 mL) was added hydroxylamine hydrochloride (210 mg, 30 mmole) and the mixture was stirred at 100° C. for 8 hrs. Solvent was removed and the residue was treated with water to remove excess of hydroxylamine. Crude material was crystallized from methanol-water to give 245 mg (85%) of the title compound. MS 575 (MH+).
