実験手順

[1,1′]-Bipiperidinyl-2,4-dione (2.00 g, 10.19 mmol) was dissolved in toluene (8 ml) and 2-chloro-4-fluorophenylamine (1.78 g, 12.23 mmol) was added. More toluene (5 ml) was added. The reaction mixture was boiled under reflux at 110° C. for 17 h then allowed to cool. When the reaction mixture reached rt the product precipitated and it was collected by filtration to yield a beige solid (1.80 g, 55%).
