Synthesis
Diethyl 1,4-dihydro-2,6-dimethyl-3,5-pyridinedicarboxylate is prepared by the reaction of formaldehyd and ethyl acetoacetate in the presence of an inert gas.
Synthesis
Hantzsch Dihydropyridine (Pyridine) Synthesis reaction allows the preparation of dihydropyridine derivatives by
condensation of an aldehyde with two equivalents of a β-ketoester in the
presence of ammonia. Diethyl 1,4-dihydro-2,6-dimethyl-3,5-pyridinedicarboxylate can be produced by using this method.
Purification Methods
recrystallization from EtOH or flash chromatography with petroleum/ethyl acetate (7:3)
