Versuchsvorschrift
6-Methylmercaptopurine riboside is synthesized by condensing 6-methylmercaptopurine with 2,3,5-tri-O-acetyl-D-ribo-furanosyl chloride using the catalyst mercuric chloride followed by deacetylation. Alternatively, 6-methylmercaptopurine riboside can be produced directly by methylation of 6-thioinosine (Fox, J. J. et al., J. Am. Chem. Soc. 80: 1669, 1958).
