We report the synthesis and X-ray crystal structure of 1,4-dihydro-2,6-dimethyl-4-(2'isopropylphenyl)-3,5-pyridine-dicarboxylic acid dimethyl ester (4), an analogue of the 1,4dihydropyridine calcium channel antagonist, nifedipine. Solution state NOE data indicate the presence of both rotameric forms
