Procedure

Diethyl 6-[2-(dimethylamino)styryl]-5-nitro-2,3-pyridinedicarboxylate is also prepared, using the above method, from N,N-dimethylbenzamide diethyl acetal and diethyl 6-methyl-5-nitro-2,3-pyridinedicarboxylate. A modification in the procedure of the latter is that upon cooling the dark red solution is partitioned between ether and water. The ethereal layer is separated and concentrated in vacuo to a dark red oil, which was carried on without purification.
