Reaction Steps

To a solution of piperidine (5.88 g, 69 mmol) and Et3N (6.98 g, 69 mmol) in EtOAc (60 mL) was added 1,2-difluoro-4-nitrobenzene (10.00 g, 63 mmol) dropwise. The mixture was stirred at rt overnight. The resulting mixture was washed with brine, dried over anhydrous Na2SO4 and concentrated in vacuo to give the title compound as a yellow solid (14.00 g, 99%).
