Versuchsvorschrift

6-(2-Fluoro-5-vinylpyridin-3-yl)-2-methyl-9-(tetrahydro-2H-pyran-2-yl)-9H-purine (1.007 g, 2.967 mmol) and 5-amino-2-methoxypyridine (0.369 g, 2.97 mmol) were dissolved in THF (25 mL) and the reaction flask was cooled in an ice water bath. Then, LiHMDS (Aldrich, St. Louis, Mo., 1.0 M in THF, 9.0 mL, 9.0 mmol) was added via syringe, and the reaction was stirred under nitrogen for 35 minutes. Then, it was poured into water (50 mL), and the layers were separated. The aqueous phase was extracted with DCM, and the organic extracts were combined, dried over sodium sulfate, filtered, concentrated, and purified on a silica gel column (40:1 DCM/2 N ammonia in MeOH to 30:1 DCM/2 N ammonia in MeOH) to give N-(6-methoxypyridin-3-yl)-3-(2-methyl-9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-yl)-5-vinylpyridin-2-amine (410.3 mg, 85% purity, 20% yield over 2 steps). MS (ESI pos. ion) m/z 444 (M+H)+.
