Reaction Steps

To a solution of (4R,5S)-4-(3-bromophenyl)-2-oxooxazolidine-5-carboxylic acid (20 mg, 0.070 mmol) in tetrahydrofuran (2 mL)/methanol (0.500 mL) was added trimethylsilyldiazomethane (0.063 mL, 0.126 mmol) dropwise at 0° C. After 3 h, the reaction was allowed to warm to ambient temperature and stirred for an additional 15 h, at which time it was concentrated in vacuo to provide (4R,5S)-methyl 4-(3-bromophenyl)-2-oxooxazolidine-5-carboxylate (18.2 mg, 0.058 mmol, 82% yield). 1H NMR (500 MHz, DMSO-d6) δ ppm 3.78 (s, 3H) 4.98 (d, J=4.88 Hz, 1H) 5.01-5.04 (m, 1H) 7.37-7.45 (m, 2H) 7.56 (s, 1H) 7.57-7.61 (m, 1H) 8.60 (s, 1H). Mass spec.: 301.77 (MH)+.
