mouse LD50 oral >32 gm/kg
mouse LD50 intraperitoneal >30 gm/kg
dog LD50 oral >12 gm/kg

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.
Diethyl 1,4-dihydro-2,6-dimethyl-3,5-pyridinedicarboxylate synthesis

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.
hantzsch pyridine synthesis

Purification Methods

recrystallization from EtOH or flash chromatography with petroleum/ethyl acetate (7:3)
