Abstract

PURPOSE: 2-Amino 1,4-dihydropyridine derivatives expressed by the formula I: [R1 is alkyl or the formula II: (A is alkylene; R2 is alkyl, H, aralkyl, phenyl; R3 is alkyl, aralkyl, phenyl, and at least one of the R2 and R3 is aralkyl or phenyl); R4 is alkyl or the formula II, and R4 is the formula II when R1 is alkyl]. For example, 2-amino-6-methyl-4-(m-nitrophenyl)-1,4-dihydropyridine-3,5-dicarboxylic acid-3-ethyl ester - 5β-(N-benzyl-N-methylamino)ethyl ester.
