Reaction Steps

3,4-Difluoronitrobenzene (1.4 mL, 2.01 g, 12.7 mmol) in piperidine (4 mL, 40.4 mmol) was heated in a sealed tube at 130° C. for 2 hours. The mixture was allowed to cool to room temperature and poured into H2O (150 mL). The title compound was separated by pipette. 1H NMR (300 MHz, DMSO-d6) δ 7.95-8.01 (m, 2H), 7.11-7.18 (m, 1H), 3.26-3.29 (m, 4H), 1.62-1.68 (m, 6H); MS (ESI+) m/z 225 (M+H)+.
