Procedure

A resealable tube was charged with (S)-2-(5-(4-(5,5-dimethyl-2-oxo-4-phenyloxazolidin-3-yl)phenyl)-6-fluoropyridin-3-yl)pyrimidine-4-carbonitrile (0.055 g, 0.12 mmol), dioxane (3.0 mL) and water (1.00 mL). Concentrated hydrochloric acid (37%)(0.25 mL) was added, the system was flushed with argon, the tube was sealed, and the reaction mixture stirred at 100° C. for 1 hour. The reaction mixture was then partitioned between EtOAc and saturated aqueous NaHCO3 solution. The aqueous phase was extracted with EtOAc. The combined organic phases were washed with brine, dried over anhydrous Na2SO4, filtered, and concentrated to afford (S)-2-(5-(4-(5,5-dimethyl-2-oxo-4-phenyloxazolidin-3-yl)phenyl)-6-oxo-1,6-dihydropyridin-3-yl)pyrimidine-4-carbonitrile (0.044 g, 0.095 mmol, 80% yield) as an off-white solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 0.92 (s, 3H), 1.65 (s, 3H), 5.49 (s, 1H), 7.22-7.45 (m, 5H), 7.50-7.61 (m, 2H), 7.63-7.76 (m, 2H), 7.93 (d, J=4.89 Hz, 1H), 8.28-8.47 (m, 2H), 9.11 (d, J=4.99 Hz, 1H), 12.33 (br.s., 1H). m/z (ESI) 464 (M+H)+.
