Abstract
An ester of p-nitrobenzoylacetic acid is cyclized under the action of hexamethyl-enetetramine and ammonium acetate to 3,5-diethoxycarbonyl-3-p-nitrobenzoyl-6-p-nitrophenyl-1,2,3,4-tetra-hydropyridine, the structure of which has been established by NMR, UV, IR, and mass spectra and also by its chemical reactions.
