Article abstract of DOI:10.1016/S0040-4039(00)79390-7

Various diethyl 1,4-dihydro-2,6-dimethyl-3,5-pyridinedicarboxylates can be oxidized, in dichloromethane at room temperature, by montmorilonite K-10 clay-supported cupric nitrate. The scope of that procedure and the effects of sonication are discussed.
