Reaction Steps

To a mixture of 4-(2,2-dioxido-3,4-dihydropyrido[2,1-c][1,2,4]thiadiazin-9-yl)phenol (200 mg), potassium carbonate (260 mg) in DMSO (4 mL) was added 1-iodo-2-methylpropane (173 mg). The mixture was stirred at 130° C. for 1 hr. Another 1-iodo-2-methylpropane (0.10 mL) was added and the mixture was stirred at room temperature overnight. 0.5N NaOHaq, 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 THF-MeOH/IPE to give the title compound (104 mg) as colorless crystals.
