実験手順

1-(Toluene-4-sulfonyl)-5-vinyl-1H-pyrrolo[2,3-b]pyridine, (200 mg, 0.67 mmol), and ethyl diazoacetate, (730 μL, 7.0 mmol), were combined in 3 mL xylene and heated to 95° C. for 30 min, then to 115° C. for 4 hours. The solvent was evaporated onder vacuum and the residue purified by silica chromatography, (eluent: methylene chloride), affording 140 mg, (50%), 2-[1-(Toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridin-5-yl ]-cyclopropanecarboxylic acid ethyl ester as a mixture of cis and trans isomers. MS ES+385.3.
