Procedure

2-Mercaptoundecanoic acid (5.0 g, 22.9 mmol), pyridine-3-aldehyde (2.16 ml, 22.9 mmol), and N-dimethylaminoethylamine (2.51 ml, 22.9 mmol) were dissolved in toluene (100 ml), and subjected to azeotropic dehydration for 2 hours. The solvent was removed from the product mixture by evaporation under reduced pressure. The residue was purified by column chromatography, giving 3-(2-dimethylam-inoethyl)-5-(n-nonyl)-2-(3-pyridyl)thiazolidin-4-one (7.9 g, 91% yield).
