実験手順
A solution of 0.52 g (3 mmol) of (2,6-dimethyl-4H-pyran-4-ylidene)malononitril and 0.3 ml (1.5 mmol) of 4,7,10-trioxa-1,13-tridecanediamine in 6 ml of acetontrile was heated to 90° C. for 70 h under nitrogen. Removal of the acetonitrile left a brown residue which was recrystallized from 25 ml methanol and 10 ml ethyl acetate yielding 0.68 g (43%) of 2-{1-[3-(2-{2-[3-(4-dicyanomethylene-2,6-dimethyl-4H-pyridin-1-yl)-propoxy]-ethoxy}-ethoxy)-propyl]-2,6-dimethyl-1H-pyridin-4-ylidene}-malononitrile.
