Abstract: 4-Substituted-1,4-dihydropyridines are prepared by a cycloaddition reaction in which the cyclization is driven to completion, after thermal reaction, by addition of an acid. Felodipine, a vasodilator, is prepared by a cycloaddition reaction of ethyl 3-aminocrotonate with a suitably substituted dichlorobenzylidine under reaction conditions whereby the product crystallizes out of the reaction solution and may be directly isolated by filtration.

Abstract: A novel procedure for bromination of aromatic moieties utilizes N-bromosuccinimide or dibromodimethylhydantoin in an aqueous alkali medium. The bromination procedure is employed for the preparation of an intermediate used in the preparation of remoxipride, an antipsychotic compound.
