실험 절차

To a mixture of 4-(2,2-dioxido-3,4-dihydropyrido[2,1-c][1,2,4]thiadiazin-9-yl)phenol (300 mg), potassium carbonate (390 mg) in DMSO (5 mL) was added bromocycloheptane (250 mg). The mixture was stirred at 130° C. for 1 hr. Another bromocycloheptane (100 uL) was added and the mixture was stirred at room temperature overnight. 0.5 N NaOH aq., EtOAc and THF were added and the extracted organic layer was washed with water and brine, dried over anhydrous sodium sulfate and concentrated in vacuo. The residue was crystallized from MeCN/IPE to give the title compound (144 mg) as colorless crystals.
