30 mg of 8-mercapto-3-methyl-7-(3-methylbut-2-enyl)-1-(2-oxo-2-phenyl-ethyl)-3,7-dihydropurine-2,6-dione were introduced into 2 ml of dimethyl-formamide and, after addition of 37 mg of potassium carbonate, stirred for 15 minutes. Then 13.5 mg of mono(2-amino-2-methylpropyl)sulfate were added, and the mixture was stirred at 80° C. for 29 hours. The volatile fractions were removed in vacuum at 40° C., and the residue was purified by column chromatography (silica gel, mobile phase: methylene chloride: methanol =95:5).
