Reaction Steps

tert-Butyl 4-(piperidin-4-yl)piperazine-1-carboxylate (1.842 g, 6.84 mmol) was added to a stirring mixture of 4-fluoro-2-methoxy-1-nitrobenzene (1.17 g, 6.84 mmol) and K2CO3 (2.83 g, 20.51 mmol) in acetonitrile (15 mL) and the reaction mixture was stirred at 90° C. for 15 h. The reaction mixture was filtered and concentrated in vacuo. The crude residue was purified by chromatography on silica gel (hexanes/EtOAc) to give the title product (2.5 g, 87%). m/z 421.
