Procedure

A recently published abstract ["Current Abstracts of Chemistry", Vol. 74, Issued 814, Item 285573, 1979] of a Polish publication [Nantkanomirski and Kaczmarek, Polish J. Pharmacol. Pharmacy 30(5), 707-12 (1978)] shows, inter alia, the reaction of 3-dimethylamino-2-(4-pyridinyl)acrolein [same as β-(dimethylamino)-α-(4-pyridinyl)acrolein] with malononitrile in the presence of sodium methoxide in methanol to produce 2-methoxy-5-(4-pyridinyl)nicotinonitrile.
