Reaction Conditions

Reaction Steps

To a mixture was sodium hydride (401 mg, 60% dispersion) in 50 ml of dimethylformamide was added 5-(chloromethyl)-5-methyl-1,3-oxazolidin-2-one (1.00 g, INTERMEDIATE 16) followed by 4-methoxybenzylchloride (1.05 g). The mixture was stirred at 90° C. for 4 h. Excess sodium hydride was quenched by addition of 3 ml of methanol. The sample was then transferred to a Biotage 65i column and purified via column chromatography on a Biotage Horizon eluting with 0% ethyl acetate in hexanes (1 column volume), followed by a gradient to 50% ethyl acetate in hexanes (over 6 column volumes), and held at 50% ethyl acetate (2 column volumes) to provide the title compound (1.41 g, 78%). Mass spectrum (ESI) 271.9 (M+2).
