Reaction Steps

A mixture of potassium carbonate (602 mg), 4-(bromomethyl)tetrahydro-2H-pyran (780 mg), 4-(bromomethyl)tetrahydro-2H-pyran (780 mg) and 4-(2,2-dioxido-3,4-dihydropyrido[2,1-c][1,2,4]thiadiazin-9-yl)phenol (602 mg) in DMSO (5 mL) was stirred at 130° C. for 3 hr. The mixture was poured into 1N NaOH aq. and extracted with EtOAc. The organic layer was separated, washed with 1N NaOH aq. and brine, dried over anhydrous magnesium sulfate and concentrated in vacuo. The residue was passed through column chromatography (NH silica gel, eluted with MeOH) to give the title compound (357 mg) as a pale yellow solid.
