실험 절차

A solution of 6-(2-fluoropyridin-3-yl)-9-(tetrahydro-2H-pyran-2-yl)-9H-purine (196.6 mg, 657 μmol) and 3-amino-6-methoxypyridine (Aldrich, St. Louis, Mo.) (101.9 mg, 821 μmol) in THF (2.0 mL) was cooled in an ice bath and treated with LiHMDS (3.0 mL, 3.0 mmol). A blood-red solution was obtained. The mixture was stirred for 1 h, and then quenched with water (0.1 mL). The mixture was extracted into EtOAc from saturated aqueous NaHCO3, concentrated and purified by flash chromatography on silica (50% EtOAc/hexane; yellow band from column) to give 6-methoxy-N-(3-(9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-yl)pyridin-2-yl)pyridin-3-amine (190 mg, 71.7% yield) as a yellow crystalline solid. 1H NMR (400 MHz, CDCl3) δ 12.06 (s, 1H); 9.68 (dd, J=7.82, 1.76 Hz, 1H); 8.99 (s, 1H); 8.44 (d, J=2.54 Hz, 1H); 8.28 (dd, J=4.69, 1.76 Hz, 1H) 8.34 (s, 1H); 8.05 (dd, J=8.90, 2.64 Hz, 1H); 6.88 (dd, J=7.82, 4.69 Hz, 1H); 6.77 (d, J=8.80 Hz, 1H); 5.86 (dd, J=10.37, 2.35 Hz, 1H); 4.16-4.25 (m, 1H); 3.95 (s, 3H); 3.82 (s, 1H); 1.98-2.24 (m, 3H); 1.61-1.89 (m, 3H). m/z (ESI, +ve) 404.0 (M+H)+.
