ethyl (2E)-4-{[7-(cyclohexylamino)-6-fluoro-1-isopropyl-4-oxo-1,4-dihydroquinolin-3-yl]oxy}but-2-enoate → Ethyl 4-{[7-(cyclohexylamino)-6-fluoro-1-isopropyl-4-oxo-1,4-dihydroquinolin-3-yl]oxy}butanoate

Participants

Reaction Steps

To an 8.0 ml ethanol solution of 280 mg of ethyl (2E)-4-{[7-(cyclohexylamino)-6-fluoro-1-isopropyl-4-oxo-1,4-dihydroquinolin-3-yl]oxy}but-2-enoate was added 28 mg of rhodium-carbon (10%) at room temperature, followed by stirring for 2 hours in an atmosphere of hydrogen. After filtration using celite, the filtrate was evaporated under a reduced pressure, and the residue was purified by silica gel column chromatography to obtain 202 mg of ethyl 4-{[7-(cyclohexylamino)-6-fluoro-1-isopropyl-4-oxo-1,4-dihydroquinolin-3-yl]oxy}butanoate.
