실험 절차

A mixture of 2-(4-oxo-3-thiazolidinyl)propionic acid (2.00 g), 2.6-dimethylaniline (1.38 g), and dicyclohexylcarbodiimide (2.35 g) in chloroform (15 ml) was refluxed for 48 hours. The resultant precipitate was removed by filtration and the filtrate was evaporated in vacuo. The residue was triturated with diethyl ether and recrystallized from ethanol to give N-(2,6-dimethylphenyl)-2-(4-oxo-3-thiazolidinyl)propionamide (1.45 g) as colorless prisms.
