Versuchsvorschrift

The cyano group of 5-amino-1-methyl-1H-imidazole-4-carbonitrile 1 is hydrolyzed to the amide in sulfuric acid to give 5-amino-1-methyl-1H-imidazole-4-carboxamide 2 which was cyclized with urea to 9-methyl-1H-purine-2,6(3H,9H)-dione 3. Chlorination of 3 yields 2,6-dichloro-9-methyl-9H-purine 4.
