実験手順
In accordance with the second procedure, the 4-alkanesulfonaminobenzoylacetonitrile is first prepared by reaction of an alkanesulfonylchloride with 4-amino-benzoylacetonitrile at room temperature in dry pyridine. This product is in turn reacted with a dialkylaminobenzaldehyde at reflux temperature in isopropyl alcohol, acetonitrile, nitromethane, or a similar polar solvent and in the presence of a catalytic amount of piperidine, or another catalyst of comparable basicity such as tetramethylguanidine or triethylenediamine, to yield the desired dye.
