The synthesis of the 2-oxides of thiazolo[3,2-a]pyrazinum salts (IV) and their deoxygenation to the title compounds (V) is described. An alternative route to the title compounds by intramolecular cyclisation of the anils formed between 2-acylthiazoles and aminoacetaldehyde dimethylacetal is also described.
