Reaction Steps

To a microwe vial with stir bar was added (R)-3-(2-chloropyrimidin-4-yl)-4-((R)-1-methoxyethyl)oxazolidin-2-one (145 mg, 0.56 mmol), potassium fluoride (327 mg, 5.63 mmol) and DMSO (4 mL). Vial capped and heated to 120° C. in a sand bath for 3 hr. Reaction mixture was then cooled to room temperature, diluted with water and aqueous mixture extracted with EtOAc. The Organic phases were combined and washed with water, brine, dried (Na2SO4), filtered and concentrated to afford a white crystalline of (R)-3-(2-fluoropyrimidin-4-yl)-4-((R)-1-methoxyethyl)oxazolidin-2-one (117 mg, 0.49 mmol, 86% yield). LCMS m/z 242.1 (M+H)+, Rt 0.63 min.
