Reaction Steps

A suspension of 6-nitro-3,4-dihydroquinolin-2(1H)-one (400 mg, 2.08 mmol), 1-(2-chloroethyl)piperidine hydrochloride(421 mg, 2.29 mmol) and potassium carbonate(862 mg, 6.24 mmol) in 10 mL DMF was stirred at room temperature overnight. After this time, the mixture was poured into 20 mL H2O then extracted with 2×50 mL CH2Cl2. The organic layer was separated, washed with brine and concentrated to give a yellow brown solid which was subjected to flash chromatography on silica gel using 5% MeOH/CH2Cl2 to give a yellow viscous oil (560 mg, 88.7%). 1H-NMR (CDCl3) δ: 8.14 (dd, J=2.7, 9 Hz, 1H), 8.06-8.05 (m, 1H), 7.24 (d, J=9.0 Hz, 1H), 4.11 (t, J=7.2 Hz, 2H), 3.02-2.95 (m, 2H), 2.73-2.67 (m, 2H), 2.57-2.48 (m, 6H), 1.59-1.44 (m, 6H).
