Reaction Steps

To a solution of 2-[4-({[3-methoxy-1-methyl-4-oxo-5-(pyridin-2-ylmethyl)-4,5-dihydro-1H-pyrrolo[3,2-c]quinolin-2-yl]carbonyl}amino)piperidin-1-yl]-2-oxoethyl acetate (60 mg) in THF (2 mL)-methanol (2 ml) was added 2N sodium hydroxide solution (2 mL), and the mixture was stirred at room temperature for 1 hr. The reaction mixture was diluted with saturated sodium hydrogen carbonate solution, and extracted twice with ethyl acetate. The extract was washed with brine, dried over magnesium sulfate, and concentrated under reduced pressure. Recrystallization from ethyl acetate-diisopropyl ether gave the title compound (25 mg, 45%) as beige crystals.
