Reaction Steps

2-(4-Bromophenyl)acetic acid (7.85 g, 36.5 mmol) and (R)-4-benzyloxazolidin-2-one (3.23 g, 18.3 mmol) were combined in toluene (30 mL) and triethylamine (10.2 mL, 73.0 mmol). The solution was then heated to 80° C., and a solution of pivaloyl chloride (4.49 mL, 36.5 mmol) in toluene (7.5 mL) was added slowly. The reaction was heated to 110° C. and stirred overnight. The reaction was then cooled, and the toluene solution was washed with 2N HCl, water, 5% Na2CO3, brine and then dried over Na3SO4. After removal of the solvent, the residue was purified by column chromatography to give (R)-4-benzyl-3-(2-(4-bromophenyl)acetyl)oxazolidin-2-one (5.65 g, 83%) as a solid.
