Sodium hydride → Ethyl 3-(5-phenoxymethyl-2-oxooxazolidin-3-yl)propionate

Participants

Reaction Steps

A procedure similar to that described in Preparation 4 was repeated, except that 113 mg of sodium hydride (as a 55% by weight dispersion in mineral oil), 10 ml of anhydrous dimethylformamide, 420 mg of 5-phenoxymethyloxazolidin-2-one (prepared as described in Preparation 112) and 471 mg of ethyl 3-bromopropionate were used, to give 463 mg of the title compound having an Rf value of 0.34 (on silica gel thin layer chromatography, using a 2:1 by volume mixture of ethyl acetate and hexane as the developing solvent).
