Procedure

2-Mercaptoundecanoic acid (7 g, 32.1 mmol), nicotinaldehyde (3.03 ml, 32.1 mmol), and ethanolamine (1.93 ml, 32.1 mmol) were added to toluene (100 ml) and subjected to azeotropic dehydration for 1 hour. The product mixture was cooled and evaporated under reduced pressure to remove the solvent. The residue was purified by column chromatography, giving 3-(2-hydroxyethyl)-5-(n-nonyl)-2-(3-pyridyl)thiazolidin-4-one (8.17 g, 73% yield).
