A process for the production of an aminoalkyl ester of 2,6-dialkyl (lower) -4-substituted phenyl-1,4-dihydropyridin-3-carboxylic acid represented by the formula: **(See formula)** where R represents a hydrogen atom or a lower alkyl group; R1 and R2, which may be the same or different, each represent a lower alkyl group; R3 represents a phenyl group that can contain a substituent or a group, aralkyl that can contain a substituent; R4 represents a hydrogen atom or a lower alkyl group; A represents a lower alkylene group; R5 represents a lower alkyl group, a lower alkoxy group, which may be substituted by a lower alkoxy group or a group (see formula) (where A, R3 and R4 have the meaning given above); and R6 represents a nitro group or a trifluoromethyl group, the procedure of which is to react a benzaldehyde derivative represented by the formula: **(See formula)** where R6 has the meaning given above, with an aminoalkyl ester represented by the formula **(See formula)** and a compound represented by the formula R1 - D-COOR5 where R, R1, R2, R3, R4 and A have the meaning given above and one of the symbols B and D represent -CO-CH2 and the other represents (see formula) (where R has the meaning given above).
