実験手順

A mixture of (2-methyl-1H-pyrrolo[2,3-b]pyridin-3-yl)-acetic acid methyl ester (100 mg, 0.49 mmol), 1-chloro-4-iodo-benzene (117 mg, 0.49 mmol), CuI (5 mg, 0.03 mmol), cyclohexane-1,2-diamine (6 μL, 0.05 mmol), potassium phosphate (218 mg, 1.0 mmol) and 1,4-dioxane (0.5 mL) is heated at 160° C. for 140 minutes. The reaction is cooled, diluted with EtOAc, filtered through silica and evaporated to dryness. The residue is purified by flash column chromatography (5:1 iso-hexane/EtOAc elution) to furnish [1-(4-chloro-phenyl)-2-methyl-1H-pyrrolo[2,3-b]pyridin-3-yl]-acetic acid methyl ester; MH+=315.
