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). NMR (CDCl3, δ) [ppm]; 0.85-0.9 (3 H, m), 2.9-3.01 (1 H, m), 3.65-3.80 (3 H, m), 3.97-4.01 (0.7 H, m), 4.02-4.07 (0.3 H, m), 5.78 (0.3 H, d, J=2.0 Hz), 5.80 (0.7 H, s).
