5,6-dimethyl-3-hydroxy-2-(3-pyridyl)isoindolin-1-one (0.30 g, 1.2 mmol) and 2-oxo-1-triphenylphosphoranylidene-pentane (0.61 g, 1.8 mmol) was heated under reflux in toluene (20 ml) under an argon atmosphere for 20 hrs. The reaction solution was concentrated under reduced pressure, and the residue was purified by silica gel chromatography (chloroform:acetone=10:1) to give 0.14 g of the title compound.
