There is a significant demand for organic nitriles, based on their versatility in reactions. Compounds prepared from nitriles have properties including superoxide inhibition, ferrielectric liquid crystal dopant, antipicornaviral agents, anti-inflammatory agents, anti-asthma agents, and fibringoen antagonists. The present invention discloses a facile synthesis for 2,4-dihydroxybenzonitrile, and ethers and diethers thereof, from 2,4-dihydroxybenzaldehyde or 2,4-dimethoxybenzaldehyde. The present invention also discloses a method of preparing a class of iron chelating agents related to desferrithiocin, all of which contain a thiazoline ring. In this method, 2,4-dihydroxybenzonitrile is condensed with (S)-2-methylcysteine.
