Reaction Steps
To a solution of N-[4-(9-chloro-5-oxo-2,3,3a,4,4a,5-hexahydro-6H-furo[2′,3′:2,3]cyclobuta[1,2-c]quinolin-6-yl)butyl]-1,3-dihydro-2H-pyrrolo[3,4-c]pyridine-2-carboxamide (30 mg, 0.064 mmol) in dimethylformamide (292 uL) and water (292 uL) was added sodium hydroxide (1.679 μl, 0.064 mmol). The solution was stirred for 18 hours and then brought to pH ˜7 by dropwise addition of 1M HCl. Column chromatography of the wet, crude mixture provided the title compound. 1H NMR (400 MHz, CDCl3) δ ppm 8.58 (s, 1H), 8.54 (d, J=5.1 Hz, 1H), 7.54 (d, J=2.4 Hz, 1H), 7.46 (dd, J=9.1, 2.4 Hz, 1H), 7.37 (d, J=9.1 Hz, 1H), 7.25 (m, 1H), 5.06 (t, J=5.7 Hz, 1H) 4.77 (bs, 2H), 4.75 (bs, 2H), 4.33 (t, J=7.4 Hz, 2H), 3.87 (m, 2H), 3.74 (m, 2H), 3.46 (m, 2H), 3.37 (dd, J=14.0, 4.5 Hz, 1H), 2.86 (dd, J=14.0, 1.3 Hz, 1H), 2.27 (m, 1H), 1.97 (m, 1H), 1.82 (m, 2H), 1.71 (m, 2H); MS (ESI(+)) m/e 467 (M+H)+.
