Procedure

To a mixture of 4-((3-chloro-4-fluorophenyl)amino)-7-methoxyquinazolin-6-ol (0.50 g, 0.16 mmol, 1.0 eq) and K2CO3 (0.05 g, 0.32 mmol, 2.0 eq) in 20 mL of DMF was added 5-(3-chloropropyl)-2,3-dimethyl-4,5,6,7-tetrahydro-2H-pyrazolo[4,3-c]pyridine (0.05 g, 0.19 mmol, 1.2 eq). The reaction mixture was heated at 80° C. for 8.0 h and concentrated in vacuo. The residue was poured into a mixture of water (100 mL) and CH2Cl2 (150 mL). The organic phase was dried over anhydrous Na2SO4 and concentrated in vacuo. The residue was purified by a silica gel column chromatography (eluting agent: 30:1 (v/v) DCM/MeOH) to give the title compound as a yellow solid (0.17 g, 21.23%), HPLC: 96.27%. The compound was characterized by the following spectroscopic data: MS (ESI, pos. ion) m/z: 513.02 (M+1); 1H NMR (400 MHz, d6-DMSO) δ: 1.93-2.18 (m, J=4.0 Hz 2H), 2.41 (s, 3H), 2.88 (s, 3H), 2.90-2.95 (m, 6H), 2.97-3.01 (m, 2H), 3.89 (s, 3H), 4.19-4.25 (m, 2H), 7.35 (s, 1H), 7.49 (t, J=8.42 Hz, 1H), 7.57-7.61 (m, 2H), 8.17 (t, J=5.66 Hz, 1H), 8.61 (s, 1H) ppm.
