Triethylamine → HCID 178498980, compound

Participants

Reaction Steps

A mixture of 2-(2-thienyl)ethyl 3-amino-2-butenoate (1.8 g) and dimethyl 3-nitrobenzylidenemalonate (2.25 g) was dissolved in anhydrous 2-propanol (80 ml) and, after addition of triethylamine (27 ml), the mixture was refluxed for 21 hours. After the solvent was distilled off under reduced pressure, the residue was purified by thin-layer silica gel chromatography (developing solvent: chloroform/methanol=19/1; elution solvent: chloroform/acetone=2/1) so as to obtain 1.0 g (26%) of the desired compound.
