100 °C

A mixture consisting of 3.73 g of 1-acetyl-4-(4-fluorobenzoyl)piperidine and 2.6 ml of morpholine was stirred at 100° C. for 24 hours and the reaction mixture was then dissolved in 100 ml of ethyl acetate. The solution was washed with a saturated aqueous solution of sodium hydrogen carbonate and water in that order and the organic layer was dried over anhydrous magnesium sulfate. The solvent was then removed and the residual oil was purified by silica gel column chromatography (eluent: methanol:dichloromethane=1:19, v/v) to give 2.4 g of the title compound as oil.
