Procedure

To a solution of (E)-3-[(1H-pyrazol-4-yl)methylidene]-1-(triphenylmethyl)piperidin-4-one (Example 98(a), 6.0 g) in acetonitrile (100 ml) were added ethyl acrylate (4.7 ml) and 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) (6.4 ml). The resulting mixture was stirred at room temperature for 15 minutes, and the reaction was stopped by an addition of a saturated aqueous sodium chloride solution. The products were extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate, and solvents were evaporated in vacuo. The residue was purified by chromatography on silica gel using a mixture of hexane, ethyl acetate and dichloromethane (2:1:1) as the eluent to afford the title compound as a yellow amorphous solid (6.12 g, yield: 82%).
