Versuchsvorschrift

A solution of 2-amino-3-methylpyridine (5.0 g., 0.0462 mole) and ethyl ethoxymethylenecyanoacetate (7.82 g., 0.0462 mole) in toluene (4 ml.) was heated for 15 minutes by means of an oil bath maintained at 100°. The solution was cooled and the title compound (9.1 g., 85%) collected by filtration. The product, m.p. 139°-143°, was recrystallized from 2-propanol to give an analytical sample, m.p. 144°-146°.
