실험 절차

To a mixture of 4-((3-chloro-4-fluorophenyl)amino)-7-methoxyquinazolin-6-ol (136 mg, 0.42 mmol, 1.0 eq) and anhydrous K2CO3 (290 mg, 2.10 mmol, 5.0 eq) in DMF (3 mL) was added a solution of (1R,5S)-3-(3-chloropropyl)-N,N-dimethyl-3-azabicyclo[3.1.0]hexan-1-amine (103 mg, 0.52 mmol, 1.2 eq) in DMF (2 mL) at room temperature. The reaction mixture was heated at 80° C. for 11 h and cooled to room temperature. Then the reaction mixture was quenched with water (5 mL) and diluted with EtOAc (10 mL). The organic phase was separated from the mixture, and the water phase was extracted with EtOAc (5 mL×3). The combined organic phases were, dried over anhydrous Na2SO4 and filtered. The filtrate was concentrated in vacuo, and the residue was purified by a silica gel column chromatography (10:1 (v/v)CH2Cl2/CH3OH) to give the crude product, which was then recrystallized from CH2Cl2/PE to afford title compound as a yellow solid (138 mg, 67.7%), HPLC: 96.5%. The compound was characterized by the following spectroscopic data: MS (ESI, pos. ion) m/z: 486.2 (M+1); 1H NMR (400 MHz, CDCl3) δ: 0.81 (1H, m), 1.11 (1H, m), 1.26 (1H, br s), 1.52 (1H, m), 2.38 (6H, s), 2.65-2.81 (3H, m), 3.11 (2H, m), 3.42 (1H, br s), 3.98 (3H, s), 4.18 (2H, t, J=6.8 Hz), 7.14 (1H, t, J=8.8 Hz), 7.25 (1H, d, J=14.4 Hz), 7.41 (1H, s), 7.66 (1H, m), 7.98 (1H, dd, J=5.2, 6.8 Hz), 8.64 (1H, s) ppm.
