Versuchsvorschrift

Taylor et al [J. Am. Chem. Soc. 81, 2442-8 (1959)] show, inter alia, the preparation of 2-(3-pyridinyl)-9H-purin-6-amine by heating the nicotinamidine salt of isonitrosomalonitrile in formamide to produce 4,6-diamino-5-nitroso-2-(3-pyridinyl)pyrimidine and heating the reaction mixture containing said 5-nitroso compound and formamide with a mixture of formic acid and sodium dithionite dihydrate to produce said 2-(3-pyridinyl)-9H-purin-6-amine, for which no use is indicated.
