Abstract
3-Ethyl 5-methyl 2-[(2-(2-(2-aminoethoxy)ethoxy)ethoxy)methyl]-4-(2-chlorophenyl)-6-methyl-1,4-dihydropyridine-3,5-dicarboxylate as new analogue of amlodipine was prepared in five steps with an overall yield of 22%. The 1,4-dihydropyridine nucleus was built in two steps via Knoevenagel reaction and the amino group of this analogue has been prepared in good yield by Staudinger reduction of the azido 1,4-dihydropyridine precursor in the last step.
