Abstract
A process for preparing aryloxymethyloxazolidinones of the following general formula: ** (See formula) ** wherein R is a hydrogen atom or an alkyl or aralkyl radical, R 'is a hydrogen atom or an alkyl group and the aryl group is mono- or dinuclear, characterized by. (1) Reacting an aryl derivative of the following general formula Arilo - 0 - M (II) wherein M is a metal that forms salts and aryl has the meaning indicated above, with an oxazolidinone of the following general formula ** (See formula) ** wherein B is a halogen atom or an arylsulfonyloxy radical, (2) and, if desired, when R in the above formula is hydrogen, alkylating the product formed in step (1) to convert R to an alkyl radical or aralkyl.
