Reaction Steps

To a solution of piperidin-4-ol (11.11 g, 0.11 mol) and Et3N (12.14 g, 0.12 mol) in EtOAc (500 mL) was added 1,2-difluoro-4-nitrobenzene (15.91 g, 0.10 mol). The mixture was stirred at rt for 24 h, and washed with water (200 mL×4). The organic phase was dried over anhydrous Na2SO4 and concentrated in vacuo to give the title compound as orange oil (19.35 g, 80%).
