Procedure

To the thus-obtained N-[trans-2-aminocyclohexyl]-3-methoxy-1-methyl-4-oxo-5-(2-oxo-2-phenylethyl)-4,5-dihydro-1H-pyrrolo[3,2-c]quinoline-2-carboxamide hydrochloride was added saturated sodium hydrogen carbonate solution, and the mixture was extracted with ethyl acetate. The extract was washed with brine, dried over magnesium sulfate, and concentrated under reduced pressure. The residue was purified by aminosilica gel chromatography (eluate; ethyl acetate/methanol=20/1), and the obtained solid was recrystallized from ethyl acetate-ethanol to give the title compound (80.0 mg, 33%) as white crystals.
