Reaction Steps

A solution of 0.30 g (1 mmol) of 2-ethylhexyl (2,6-dimethyl-pyran-4-ylidene)cyanoacetate (prepared as described in example 1) in 4 ml butylamine was refluxed at 80° C. for 1 h under nitrogen. Removal of the excess of butylamine at reduced pressure left a orange oil which was purified by FC (n-hexane/EtOAc 1:1) yielding 0.23 g (64%) of 2-ethylhexyl (1-N-butyl-2,6-dimethyl-1H-pyridin-4-ylidene)cyanoacetate as a slightly yellow solid.
