実験手順

To a freshly prepared solution of sodium methoxide (108 mg, 1.96 mmol) in methanol (2 ml), a solution of 6-ethyl-3-methyl-4-phenyl-6H-isoxazolo[3,4-d]pyridazin-7-one (500 mg, 1.96 mmol) (Dal Piaz, V.; Giovannoni, M. P.; Castellana, C.; et al, J. Med. Chem. 1997, 40, 1417-1421) in of dry methanol (2 ml) was added and the mixture was stirred for a while. Then, benzaldehyde (0.40 ml, 3.92 mmol) was added dropwise and the final mixture was refluxed for 2 hours. The resulting suspension was let to cool down and the final product (514 mg, 76%-yield) was collected by filtration.
