Reaction Steps

To a solution of 4-piperidone hydrochloride monohydrate (10.0 g, 0.065 mol) in DMF (80 mL) are added 4-Fluoro-2-methoxy-1-nitro-benzene (10.0 g, 0.058 mol) and potassium carbonate (20.2 g), and the mixture is stirred at 70° C. for 20 h. After a filtration, the filtrate is poured into H2O (ca. 300 mL), and the resulting precipitates are collected by a filtration followed by washing with H2O for several times to give title compound (8.98 g) in 61% yield. Orange solid.
