Reaction Steps

To a solution of (4R,5S)-2-oxo-4-(3-(phenylethynyl)phenyl)oxazolidine-5-carbonitrile (35 mg, 0.121 mmol) in Toluene (2 mL) was added triethylamine hydrochloride (50.6 mg, 0.364 mmol) and sodium azide (23.68 mg, 0.364 mmol) and the reaction was heated to reflux. After 2 days, the reaction was poured into water (1 ml) and extracted with ethylacetate (10 mL×2). The combined organic layers were dried over magnesium sulfate, filtered, and concentrated to an off white solid that was purified by Preparative HPLC method 4 providing (4R,5S)-4-(3-(phenylethynyl)phenyl)-5-(1H-tetrazol-5-yl)oxazolidin-2-one (30 mg, 0.090 mmol, 73.8% yield) 1H NMR (500 MHz, DMSO-d6) δ ppm 5.21-5.55 (m, 2H) 7.10 (br. s., 3H) 7.34 (d, J=7.93 Hz, 1H) 7.39-7.49 (m, 4H) 7.51 (d, J=7.32 Hz, 1H) 7.57 (dd, J=6.41, 3.05 Hz, 2H) 8.27 (s, 1H). Mass spec.: 331.99 (MH)+.
