Versuchsvorschrift

Hydrochloride of 1-ethyl-3-[3-(N,N-dimethylamino)propyl]carbodiimide (250 mg) was added to a chloroform (15 mL) solution of 4-chloro-2-(cyclopentylamino)benzoic acid (250 mg) and 7-amino-1-methyl-3,4-dihydroquinolin-2(1H)-one (184 mg), followed by stirring at room temperature for 26 hours. The reaction liquid was concentrated under a reduced pressure. By purifying the residue by silica gel column chromatography (chloroform:methanol, 1:0 to 9:1), 4-chloro-2-(cyclopentylamino)-N-(1-methyl-2-oxo-1,2,3,4-tetrahydroquinolin-7-yl)benzamide was obtained. By treating this with 4 M hydrogen chloride/ethyl acetate solution, 4-chloro-2-(cyclopentylamino)-N-(1-methyl-2-oxo-1,2,3,4-tetrahydroquinolin-7-yl)benzamide hydrochloride (97 mg) was obtained as a solid.
