    4-Substituted-l,4-dihydropyridines of formula I are prepared by a cycloaddition reaction in which the cyclization is driven to completion at ambient temperature optionally in water without any catalyst. For exemplary purposes, the invention is described in particular detail with respect to the preparation of felodipine of formula II. Felodipine, a vasodilator, is prepared by a cycloaddition reaction of alkyl 3- aminocrotonate with dichlorobenzylidene under reaction conditions whereby the product crystallizes out of the reaction solution and may be directly isolated by filtration.
