Reaction Steps

To a solution of 4-((3-chloro-4-fluorophenyl)amino)-7-methoxyquinazolin-6-ol (60 mg) in DMF (6 mL) was added K2CO3 (66 mg) and tetrabutylammonium iodide (5 mg). The mixture was stirred for 10 min at room temperature, to this, a solution of 2-(3-chloropropyl)octahydropyrano[3,4-c]-pyrrole (38 mg) in DMF (1 mL) was added. The reaction mixture was heated at 90° C. for 12 h under N2 and CH2Cl2 (100 mL) was added. Then the mixture was washed with water followed by brine, dried over anhydrous Na2SO4 and concentrated in vacuo. The residue was chromatographed with a silica gel column (eluting agent: 20:1 (v/v) CH2Cl2/CH3OH) to give the title compound (40 mg, 43.95%), HPLC: 98.50%. The compound was characterized by the following spectroscopic data: MS (ESI, pos. ion) m/z: 488.0 (M+1); 1H NMR (400 MHz, CDCl3) δ: 1.26-1.29 (m, 2H), 1.37 (s, 3H), 2.33-2.37 (m, 3H), 2.59 (s, 1H), 3.03 (s, 1H), 3.44-3.47 (m, 1H), 3.50 (s, 1H), 3.72 (d, J=3.28 Hz, 1H), 3.78 (d, J=1.76 Hz, 1H), 3.81 (s, 1H), 3.87-3.89 (m, 1H), 3.99 (s, 3H), 4.50-4.55 (m, 2H), 7.11 (t, J=17.68 Hz, 1H), 7.25 (d, J=15.28 Hz, 1H), 7.35 (m, 1H), 7.82-7.86 (m, 1H), 8.13 (s, 1H), 8.22-8.25 (m, 1H), 8.63 (s, 1H), 8.92 (s, 1H) ppm.
