Hydrochloric Acid → HCID 66703837, compound

Participants

Reaction Steps

A mixture of [7-{[2-(cyclohexylamino)-4-(trifluoromethyl)benzoyl]amino}-2-oxo-3,4-dihydroquinolin-1(2H)-yl]acetic acid (70 mg), N,N′-carbonyldiimidazole (70 mg), methylamine aqueous solution (1 mL) and THF was stirred at room temperature for 3 hours, mixed with methanol and stirred for 20 minutes. A 0.5 M hydrochloric acid was added to the reaction liquid, followed by extraction with ethyl acetate. The organic layer was concentrated under a reduced pressure, and the residue was purified by silica gel column chromatography (chloroform:methanol, 20:1 to 10:1) to obtain 2-(cyclohexylamino)-N-{1-[2-(methylamino)-2-oxoethyl]-2-oxo-1,2,3,4-tetrahydroquinolin-7-yl}-4-(trifluoromethyl)benzamide (12 mg) as a solid.
