Reaction Steps
A solution of (R)-4-((R)-1-(tert-butoxy)ethyl)-3-(2-fluoropyrimidin-4-yl)oxazolidin-2-one (1.0 g, 3.35 mmol) in 20 ml of DCM was cooled in an ice bath, and treated with 8.16 mL of TFA. The mixture was stirred at same temperature for 4 hours, and allowed to warm to room temp and stir 16 h. The reaction was poured into 10 mL water. The DCM was removed in vacuo. The aqueous was basified by slow addition of saturated NaHCO3 solution, then extracted with (2×mL) EtOAc. The organics were washed with 30 mL brine, and dried over Na2SO4. Filtered and concentrated to give the desired alcohol, (R)-3-(2-fluoropyrimidin-4-yl)-4-((R)-1-hydroxyethyl)oxazolidin-2-one (0.56 g, 70% yield) as a white solid. HRMS(B) tR=0.80 min; MS m/z 228.4 (M+H)+.
