실험 절차

A mixture of ethyl 5-[7-ethyl-2-(hydroxymethyl)-4-(5-methyl-3-pyridinyl)pyrrolo[1,2-b]pyridazin-3-yl]pentanoate (100 mg), 1H-isoindole-1,3(2H)dione (44.6 mg) diisopropyl azodicarboxylate (76.7 mg) and triphenylphosphine (995 mg) in tetrahydrofuran (2 mL) was stirred at ambient temperature for 1 hour. After evaporation of solvent, the residue was purified by silica gel column chromatography eluting with a mixture of hexane and ethyl acetate (20:1–1:1) to give ethyl 5-[2-[(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)methyl]-7-ethyl-4-(5-methyl-3-pyridinyl)pyrrolo[1,2-b]pyridazin-3-yl]pentanoate as yellow oil (107 mg).
