Reaction Steps

A stirred slurry of 5 g (0.0163 mole) of 3-[3-(trifluoromethyl)phenoxy]azetidine oxalate in 50 ml of tetrahydrofuran was treated with 5 ml of triethylamine and after 1 hr, 2.5 g (0.018 mole) of diethylcarbamoyl chloride was added. After stirring an additional 15 hr, the reaction was treated with 10 ml of water and saturated with calcium chloride. The tetrahydrofuran was decanted from the solid residue and concentrated in vacuo to an oil. The crude oil was chromatographed on a Water's Prep-LC using 50% ethyl acetate/toluene as the eluent. After concentration of the main fractions 3.1 g (60.1%) of pale yellow oil was obtained.
