PROCEDURE

实验过程

A suspension of 2-[(1,2,3,4-tetrahydro-5-hydroxy-2-naphthyl)methyl]-6-diphenylmethyl-3(2H)-pyridazinone (425 mg), ethyl bromoacetate (184 mg) and potassium carbonate (152.9 mg) in acetonitrile (15 ml) was refluxed for 6 hours. After cooling, the precipitated solid was filtered off and the filtrate was evaporated in vacuo. The residue was purified by silica gel column chromatography (n-hexane:ethyl acetate=1:1) to give 2-[(1,2,3,4-tetrahydro-5-ethoxycarbonylmethoxy-2-naphthyl)methyl]-6-diphenylmethyl-3(2H)-pyridazinone (0.43 g) as pale yellow oil.
