실험 절차

100 mg 6-hydroxy-2-(3-methoxy-6-pyridin-4-yl-pyridazin-4-yl)-indole-1-carboxylic acid tert-butyl ester and 175 mg triphenylphosphine are dissolved in 7 mL toluene and 2 mL THF. After dropwise addition of 84 μL 2-dimethylaminoethanol and 123 □L diethyl azodicarboxylate, the reaction mixture is stirred at room temperature for 5 hours. The solvent is removed in vacuo and the residue dissolved in dichloromethane. The organic phase is ished with water and the aqueous phase extracted twice with dichloromethane. The combined organic phases are dried over MgSO4 and concentrated in vacuo. Purification by HPLC afforded 35 mg (43%) 6-(2-dimethylaminoethoxy)-2-(3-methoxy-6-pyridin-4-yl-pyridazin-4-yl)-indole-1-carboxylic acid tert-butyl ester.
