実験手順

To a suspension of 4-(2,3-dimethylindol-5-yloxy)-7-hydroxy-6-methoxyquinazoline (124 mg, 0.32 mmol) in methylene chloride (2.5 ml) was added triphenylphosphine (179 mg, 0.628 mmol), 1-(2-hydroxyethyl)pyrrolidine (75 mg, 0.65 mmol) followed by diisopropyl azodicarboxylate (134 μl, 0.68 mmol) in portions. After stirring overnight at ambient temperature the mixture was poured onto a column of silica and eluted with ethyl acetate/methyl ene chloride (1/1) followed by ethyl acetate/methylene chloride/methanol (4/5/1) followed by methylene chloride/methanol (9/1). After removal of the solvent, the solid was triturated with ether, filtered, washed with ether and dried under vacuum to give 4-(2,3-dimethylindol-5-yloxy)-6-methoxy-7-(2-(pyrrolidin-1-yl)ethoxy)quinazoline (51 mg, 37%).
