摘要
A synthesis of 5-(3,3-dimethyl-3H-indol-2-yl)-3-methyl-1H-pyrazolo[3,4-b]pyridines by the reaction of variously substituted aminomethylene malondialdehydes [2-(3,3-dimethyl-3H-indol-2-ylidene)malondialdehydes] with 5-amino-1-aryl-3-methylpyrazoles in the presence of p-toluenesulfonic acid in water is described.
