Formation of derivatives of thiazoline by the reaction of thiourea with 2-bromo-3-aminopropionic acid
Depending on the conditions employed, thiourea reacts with the hydrobromide of 2-bromo-3-aminopropionic acid to give a dihydrobromide or an internal salt S-(2-amino-1-carboxyethyl)isothiourea. This compound can also lose ammonia to give a thiazoline derivative.
