To a suspension of anhydrous potassium carbonate (11.80 g, 85.90 mmol) in DMF (30 ml) was added a solution of 4-piperidinone (7.20 g, 47.2 mmol) in DMF (5 ml) followed by the addition of 3,4,5-trifluoronitrobenzene (7.00 g, 42.8 mmol) and stirred at room temperature for 3 h. The reaction mixture was poured onto ice water and the resulting solid was filtered off. Drying the solid under vacuum yielded the title compound as yellow powder (4.50 g, 45%).
