The present invention relates to processes for the preparation of oxazolidinone derivatives. More particularly the present invention provides processes for the preparation of 5-chloro-N-( (5S)-2-oxo-3-[4-(3-oxo-4-moφholinyl)phenyl]-1,3-oxazolidin-5-yl methyl)-2-thiophene-carboxamide and intennediates thereof. Where L is a leaving group like halogen atom (F, CI, Br, I) or -OS02R where R = C'-4 alkyl straight chain or branched chain, sub or unsubstituted aryl, sub or unsub aryl alkyl; with a suitable reagent to provide the compound of formula (II). The reaction step is performed by reacting the compound of formula (IV) with amine source which may be dissolved in solvent like water or alcohol. For example ammonium hydroxide.
