To a solution of 4-((3-chloro-4-fluorophenyl)amino)-7-methoxyquinazolin-6-ol (0.19 g) in DMF (6 mL) was added K2CO3 (0.42 g) and tetrabutylammonium iodide (20 mg). The mixture was stirred at room temperature for 10 min, to this, a solution of 5-(3-chloropropyl)hexahydro-1H-furo[3,4-c]pyrrole (0.13 g) in DMF (2 mL) was added. The reaction mixture was heated at 80° C. for 14 h under N2 and treated with CH2Cl2 (100 mL), then washed with water and brine. The mixture was dried over anhydrous Na2SO4 and filtered. The filtrate was concentrated in vacuo and the residue was chromatographed with a silica gel column (eluting agent: 20:1 (v/v) CH2Cl2/CH3OH) to give the title compound (180 mg, 60.04%), HPLC: 95.78%. The compound was characterized by the following spectroscopic data: MS (ESI, pos. ion) m/z: 474.0 (M+1); 1H NMR (400 MHz, CDCl3) δ: 2.12 (t, J=13.28 Hz, 2H), 2.54 (s, 2H), 2.72 (t, J=13.32 Hz, 2H), 2.83 (d, J=9.00 Hz, 2H), 2.90 (s, 2H), 3.73 (t, J=5.36 Hz, 3H), 3.99 (s, 3H), 4.28 (t, J=13.24 Hz, 2H), 7.15 (t, J=17.60 Hz, 1H), 7.25 (d, J=7.32 Hz, 1H), 7.44 (s, 1H), 7.60-7.64 (m, 1H), 7.93-7.96 (m, 1H), 7.99 (s, 1H), 8.64 (s, 1H) ppm.
