The condensation of 4-(2-phthalimidoethoxy)acetoacetic acid ethyl ester (I) with 2-chlorobenzaldehyde (II) by means of piperidine in isopropanol gives 2-(2-chlorobenzylidene)-4-(2-phthalimidoethoxy)acetoacetic acid ethyl ester (III), which is cyclized with 3-aminocrotonic acid methyl ester (IV) in hot isopropanol to yield the phthalimido amlodipine (V). Finally, this compound is deprotected by means of aqueous methylamine to afford the target amlodipine.
