Versuchsvorschrift
2-Methylthio-4-[5-aminobenzimidazol-1-yl]pyrimidine (EXAMPLE 3, 513 mg) was dissolved in diiodomethane (5 mL), isoamylnitrite (0.32 mL) was added and the resulting solution was heated to 100° C. for 30 minutes. Upon cooling to rt, the reaction mixture was directly purified by column chromatography (SiO2, 5% MeOH in CH2Cl2) to yield 342 mg of the title compound. Mass spectrum 371.1 (ESI) (M+).
