Application of alkyl iodide to 3-(2-methyl-4-amino-5-pyrimidylmethyl)-3a-methyltetrahydrofuro [2, 3-d] thiazoline-2-thione (III) and 4-hydroxy-4-methyl-5 β-hydroxyethylthiazolidine-2-thione, and its acyl derivative (IV) affords, according to the amount of the alkyl iodide used and reaction conditions, mono or dihydriodide of thiochromine (II). It was shown in the present series of experiments that (II) is formed from (III) and (IV), respectively through the intermediates (V) and (VI).
