Reaction Steps

Under N2, a solution of N-(2-hydroxyethyl)aniline (500 mg, 3.65 mmol) and triethylamine (1 mL, 7.29 mmol) in THF (2 mL) was added slowly to a solution of triphosgene (360 mg, 1.21 mmol) in THF (2 mL) at 0° C. The reaction mixture was stirred at 0° C. for one hour. The reaction was then quenched with a saturated solution of sodium bicarbonate (4 mL) and extracted with methylene chloride (3×4 mL). The organic extracts were dried over sodium sulfate and concentrated. Silica gel chromatography (5%-35% EtOAc/CH2Cl2) gave 3-phenyl-1,3-oxazolidin-2-one. LCMS (ES) m/z 164.2 (M+H)+.
