実験手順

To a solution of (4R)-4-(hydroxymethyl)-5-(1-hydroxypropan-2-yl)oxazolidin-2-one (1.0 equiv.) in pyridine (0.15 M) at 0° C. was added p-toluenesulfonylchloride (2.1 equiv.). The solution was allowed to warm to rt as it stirred for 14 hours, at which time EtOAc was added and the solution was washed with H2O (3×), CuSO4(sat.) (2×), H2O, Na2CO3(sat.) and NaCl(sat.), dried over MgSO4, filtered, concentrated and purified by silica gel chromatography (75% EtOAc/hexanes eluent) yielding 2-((4R)-2-oxo-4-(tosyloxymethyl)oxazolidin-5-yl)propyl 4-methylbenzenesulfonate (68%). LCMS (m/z): 484.1 (MH+); LC Rt=4.06 min.
