2-bromo-5-nitrothiazole (2) with weakly basic secondary aliphatic amines gives the expected 2-amino productsfrom nucleophilic displacement of the bromine, reaction of the isomeric 5-bromo-2-nitrothiazole (3) with such amines gives mixtures of the expected 5-amino products together with 2-aminated 5-nitrothiazole rearrangement products. The identity of the latter were detemined by alternative synthesis, and by X-ray
