The 5-Amino-1-β-ribofuranosylimidazole-4-carboxamide (1.3 g, 5 mmol) was dissolved in pyridine and 18 ml (15 mmol) phenyl-isothiocyanate were added slowly. The reaction mixture was refluxed for 2 hours under argon atmosphere. The solution was cooled to room temperature, the precipitate collected by filtration and washed with diethyl ether. The obtained pyridinium salt of the product was dissolved in aqueous sodium hydroxide (15%, 40 ml). The solution was heated 30 minutes at 60° C. and concentrated under vacuum. Methanol was then added and the solution was kept in the refrigerator overnight. After 20 hours the precipitated colourless prisms were collected by filtration to give 1.2 g (80%) 2-Mercaptoinosine.
