Procedure

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)-3-azabicyclo[3.1.0]hexan-1-ol (92 mg, 0.52 mmol, 1.2 eq) in DMF (2 mL) at rt. The mixture was heated at 80° C. for 7 h, then cooled to room temperature and quenched with H2O (10 mL). The mixture was diluted with EtOAc (20 mL). The water layer was then extracted with EtOAc (5 mL×3). The combined organic phases were dried over anhydrous Na2SO4 and concentrated in vacuo. The residue was chromatographed with a silica gel column (10:1 (v/v) CH2Cl2/CH3OH) to give the crude product, which was recrystallized from CH2Cl2/PE to afford the title compound as a pale yellow solid (90 mg, 46.70%), HPLC:91.67%. The compound was characterized by the following spectroscopic data: MS (ESI, pos. ion) m/z: 459.2 (M+1); 1H NMR (400 MHz, CDCl3) δ: 0.83 (2H, m), 1.09 (1H, t, J=4.8 Hz), 1.36 (1H, m), 2.57 (2H, m), 2.72 (1H, d, J=8.8 Hz), 3.05 (1H, d, J=8.4 Hz), 3.56 (2H, m), 3.80 (2H, m), 3.99 (3H, s), 4.12 (2H, t, J=6.8 Hz), 7.14 (1H, t, J=8.8 Hz), 7.23 (1H, s), 7.29 (1H, d, J=15.8 Hz), 7.60 (1H, m), 7.89 (1H, dd, J=2.5, 6.5 Hz), 8.63 (1H, s) ppm.
