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.
本发明涉及制备氧唑烷衍生物的过程。更具体地说,本发明提供了制备5-氯-N-((5S)-2-氧代-3-[4-(3-氧代-4-吗啡基)苯基]-1,3-氧唑烷-5-基甲基)-2-噻吩羧酰胺及其中间体的过程。其中L是离去基团,如卤原子(F、Cl、Br、I)或-OSO2R,其中R = C'-4烷基直链或支链、取代或未取代芳基、取代或未取代芳基烷基;使用适当的试剂来提供式(II)的化合物。反应步骤通过将式(IV)的化合物与胺源反应来进行,胺源可以溶解在水或醇等溶剂中,例如氢氧化铵。
