실험 절차
Triethylamine (20 ml, 145 mmoles) was dropwise added to a suspension of 5,6-dimethoxy-3-(triphenyl-λ6-phosphanyl)-3H-isobenzofuran-1-one (78 g, 145 mmoles), obtained as described in example 3, and 4-pyridincarboxaldehyde (13 ml, 145 mmoles) in CH2Cl2 (1 l), at room temperature under stirring. After 1.5 hours the mixture was filtered and evaporated and the residue was treated with ethanol under reflux, cooled and filtered. The mother liquors were chromatographed (eluent: 100% CH2Cl2, then with 1% CH3OH) and the residue was brought to dryness and joined to the above filtrate to give 25 g of the title compound.
