実験手順

A mixture of ethyl 7-(4-fluorobenzoyl)-8-oxononanoate (300 mg), (1-amino-5-ethyl-1H-pyrrol-2-yl)(4-fluorophenyl)methanone (216 mg), and p-toluenesulfonic acid monohydrate (35.4 mg) in ethanol (6 ml) was refluxed for 5 hours. The mixture was partioned between ethyl acetate and water. The organic layer was separated, washed with brine, dried over magnesium sulfate, and evaporated. The residue was chromatographed on silica gel eluting with a mixture of ethyl acetate and hexane (1:4) to give ethyl 6-[7-ethyl-2,4-bis(4-fluorophenyl)pyrrolo[1,2-b]pyridazin-3-yl]hexanoate (83 mg) and ethyl 6-[7-ethyl-4-(4-fluorophenyl)-2-methylpyrrolo[1,2-b]pyridazin-3-yl]hexanoate (40 mg) as an oil.
