Reaction Steps

To a solution of tert-butyl (1-(2-fluorophenyl)-2-hydroxy-2-methylpropyl)carbamate (400 mg, 1.41 mmol) in THF (8 mL) was added potassium tert-butoxide (316.87 mg, 2.82 mmol) at 0-5° C. The resulting reaction mixture was stirred for 2 hours at ambient temperature. After completion of the reaction (monitored by TLC, TLC system: 50% EtOAc in hexane), the reaction mixture was quenched with ice water and extracted with EtOAc. The combined organic layers were washed with, water, saturated NaCl solution and dried on Na2SO4, filtered, and concentrated under reduced pressure to afford 4-(2-fluorophenyl)-5,5-dimethyloxazolidin-2-one (290 mg, 98.18%) as an off-white solid. 1H NMR (400 MHz, DMSO-d6): δ 8.05 (s, 1H), 7.44-7.35 (m, 2H), 7.30-7.22 (m, 2H), 4.88 (s, 1H), 1.53 (s, 3H), 0.88 (s, 3H). m/z (ESI) 210.1 (M+H)+.
