Versuchsvorschrift

To a solution of 8-bromo-2-[(1-methylbutyl)oxy]-9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-amine (493 mg) in dry MeOH (4.37 mL) was added sodium methoxide solution (0.722 mL, 30% wt. in MeOH) and the mixture was stirred at reflux for 6 h. A further portion of sodium methoxide solution (0.120 mL, 30% wt. in MeOH) was added and the reaction was continued for 90 mins. The reaction was cooled and concentrated in vacuo to give an orange residue. The residue was taken up in saturated ammonium chloride (25 mL) and washed with EtOAc (25 mL). The organics were separated and washed with water (15 mL). The organics were separated, dried over MgSO4, filtered and concentrated in vacuo to give the title compound as an orange foam (313 mg).
