(S)-N-((3-(3-fluoro-4-(piperazin-1-yl)phenyl)-2-oxooxazolidin-5-yl)methyl)acetamide → 9-(4-{4-[(5S)-5-(Acetylamino-methyl)-2-oxo-oxazolidin-3-yl]-2-fluoro-phenyl}-piperazin-1-yl)-8-fluoro-3-methyl-6-oxo-2,3-dihydro-6H-1-oxa-3,3a-diaza-phenalene-5-carboxylic Acid Ethyl Ester

Participants

Reaction Steps

A solution of 100 mg 8,9-difluoro-3-methyl-6-oxo-2,3-dihydro-6H-1-oxa-3,3a-diaza-phenalene-5-carboxylic acid ethyl ester (0.32 mmol) and 216 mg of N-[{(5S)-3[3-fluoro-4-(1-piperazinyl)phenyl]-2-oxo-5-oxazolidinyl}-methyl]-acetamide (0.64 mmol) were dissolved in a mixture of 1 ml pyridine and 1 ml DMSO. The reaction was monitored by TLC. The DMSO was evaporated, the residue digested in water and the solid collected. The solid was purified by chromatography, using a 9/1 dichloromethane/methanol mixture as eluent.
