실험 절차

To a cold (0° C.) solution of 1,2-thiazinane 1,1-dioxide (32 mg, 0.24 mmol) in anhydrous DMF (2 mL) under an atmosphere of nitrogen, a solution of lithium bis(trimethylsilyl)amide in THF (0.18 mL, 1M) was added. After stirred at room temperature for 20 minutes, solid 2-(4-fluorobenzyl)-10-methoxy-4-(1-chloroethyl)-8-methyl-7,8-dihydropyrazino[1′,2′:1,5]pyrrolo[2,3-d]pyridazine-1,9(2H,6H)-dione (50 mg. 0.12 mmol) was added and the reaction mixture was stirred at room temperature overnight. The product mixture was concentrated under vacuum. The residue was partitioned between dichloromethane and dilute hydrochloric acid. The organic extract was washed with brine, dried over anhydrous magnesium sulfate, filtered, and concentrated under vacuum to afford the title compound. ES MS M+1=518
