実験手順
6-(5-(1,3-Dioxolan-2-yl)-2-fluoropyridin-3-yl)-2-methyl-9-(tetrahydro-2H-pyran-2-yl)-9H-purine (4.557 g, 11.82 mmol) and 5-amino-2-methoxypyridine (1.507 g, 12.14 mmol) were dissolved in tetrahydrofuran (80 mL) and cooled in an ice water bath. Then, LiHMDS (Aldrich 1.0 M in THF, 36.0 mL, 36.0 mmol) was added via syringe over about 10 minutes. The reaction was stirred under nitrogen at 0° C. for 40 minutes, and then the reaction was treated with water (100 mL) and warmed to room temperature. The layers were separated, and the aqueous phase was extracted with DCM. The aqueous phase was diluted with brine and extraction with DCM was continued. The combined organic extracts were combined, dried over sodium sulfate, filtered, concentrated, and purified on a silica gel filter (600 mL fritted filter, about 3 inches of silica gel, 80:1 DCM/2N ammonia in MeOH to 50:1 DCM/2N ammonia in MeOH) to give 5-(1,3-dioxolan-2-yl)-N-(6-methoxypyridin-3-yl)-3-(2-methyl-9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-yl)pyridin-2-amine (4.500 grams, 71% purity, 52% yield over two steps). MS MS (ESI pos. ion) m/z 446. Calculated exact mass for C23H23N7O3: 445 (M+—C2H4O). 1H NMR (CDCl3, 400 MHz) δ 12.69 (s, 1H), 9.91 (s, 1H), 8.44 (d, J=2.74 Hz, 1H), 8.41 (d, J=2.15 Hz, 1H), 8.29 (s, 1H), 8.23 (dd, J=8.80 Hz, 2.74 Hz, 1H), 6.79 (d, J=8.80 Hz, 1H), 5.94 (s, 1H), 5.87 (dd, J=10.56 Hz, 2.15 Hz, 1H), 4.24-4.17 (m, 3H), 4.12-4.05 (m, 2H), 3.96 (s, 3H), 3.88-3.79 (m, 1H), 2.91 (s, 3H), 2.19-2.00 (m, 3H), 1.93-1.77 (m, 3H).
