Ethyl ((5-chlorothiophen-2-yl)sulfonyl)carbamate → 5-chloro-N-({[7-(cyclohexylamino)-6-fluoro-1-isopropyl-4-oxo-1,4-dihydroquinolin-3-yl]amino}carbonyl)thiophene-2-sulfonamide

Reaction Steps

287 mg of ethyl [(5-chloro-2-thienyl)sulfonyl]carbamate was dissolved in 5.0 ml of toluene, and 250 mg of 3-amino-7-(cyclohexylamino)-6-fluoro-1-isopropylquinolin-4(1H)-one was added, followed by overnight stirring at 110° C. The reaction mixture was cooled to room temperature and concentrated under a reduced pressure. Then, ethyl acetate was added and the insoluble materials were collected by filtration, thereby obtaining 280 mg of 5-chloro-N-({[7-(cyclohexylamino)-6-fluoro-1-isopropyl-4-oxo-1,4-dihydroquinolin-3-yl]amino}carbonyl)thiophene-2-sulfonamide.
