Procedure

A solution of 3-cyano-1-(4-nitro-benzoyl)-pyrrolo[1,2-a]quinoline (44.3 mg, 0.130 mmol), 5 wt % Palladium on Carbon (23.4 mg), ethanol (12.0 mL), and ethyl acetate (90.0 mL) was agitated under hydrogen (30 PSI) for 1.5 h. The solution was filtered through Celite and purified by flash column chromatography (9:1 dichloromethane/ethyl acetate) to yield 5.3 mg (13%) of a light brown solid. 1H NMR (DMSO-d6): 8.04 (d, J=6.86 Hz, 1H), 7.88 (d, J=9.34 Hz, 1H), 7.81 (d, J=8.79 Hz, 2H), 7.75 (d, J=9.07 Hz, 2H), 7.55–7.70 (m, 3H), 6.66 (d, J=8.79 Hz, 2H), 6.42 (s, 2H).
