実験手順

A glass microwave reaction vessel was charged with 6-(2-fluoropyridin-3-yl)-2-methyl-9-(tetrahydro-2H-pyran-2-yl)-9H-purine (100 mg, 0.319 mmol) and N-(4-aminophenyl)cyclopropanecarboxamide (56.2 mg, 0.319 mmol, Enamine Ltd, Ukraine) in THF (5 mL), argon was bubbled through for 2 min, and the tube was sealed. The reaction mixture was cooled to 0° C. and lithium bis(trimethylsilyl)amine (1 N in THF, 1 mL, 1 mmol) was added dropwise. The red solution was stirred at 0° C. for 1 h and then warmed to room temperature. The mixture was quenched with saturated NH4Cl and extracted with EtOAc (3×). The organic extract was washed with satd NaCl and dried over Na2SO4. The solution was filtered and concentrated in vacuo. The crude material was purified by chromatography through a Redi-Sep pre-packed silica gel column (25 g) eluting with a gradient of 2% to 5% 2 M NH3.MeOH in DCM to give N-(4-(3-(2-methyl-9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-yl)pyridin-2-ylamino)phenyl)cyclopropanecarboxamide (90 mg, 0.192 mmol, 60% yield) as a yellow solid. 1H NMR (400 MHz, d6-DMSO) δ 12.69 (s, 1H); 10.12 (s, 1H); 9.73 (dd, J=7.92, 1.86 Hz, 1H); 8.87 (s, 1H); 8.35 (dd, J=4.70, 1.76 Hz, 1H); 7.76 (d, J=9.00 Hz, 2H); 7.57 (d, J=8.80 Hz, 2H); 6.99 (dd, J=7.82, 4.69 Hz, 1H); 5.84 (dd, J=10.95, 1.76 Hz, 1H); 4.04 (d, J=12.63 Hz, 1H); 3.71-3.81 (m, 1H); 2.91 (s, 3H); 2.27-2.38 (m, 1H); 1.97-2.07 (m, 2H); 1.73-1.85 (m, 2H); 1.56-1.67 (m, 2H); 0.72-0.82 (m, 4H). m/z (ESI, +ve ion) 470 (M+H)+.
