Abstract:Rivaroxaban was synthesized by a four-step reaction: at first the epoxy-opening reaction of 4-(4-aminophenyl)morpholin-3-one(2)with 2-[(2S)-oxiran-2-ylmethyl]-1H-isoindole-1,3(2H)-dione(3); then the cyclization reaction of the epoxy-opening reaction product with bis(trichloromethyl)carbonate to form oxazolidin-2-one; then oxazolidin-2-one was deprotected using methylamine; at last, amidation of the deprotected oxazolidin-2-one with 5-chlorothiophene-2-carbonyl chloride to give the final product. The structure of rivaroxaban was proved using 1H NMR and MS spectra, and the total yield of the target product was 76.8%. |
