Procedure

A mixture of N-(3-chloro-4-fluorophenyl)-6-(3-chloropropoxy)-7-methoxyquinazolin-4-amine (1.50 g), K2CO3 (5.00 g) and 1-ethyloctahydro-1H-pyrrolo[3,4-b]pyridine (0.90 g) in 25 mL of DMF was stirred for 7 h at 80° C., and then cooled down. The resulted mixture was poured into 50 mL of ice-water and extracted with CH2Cl2 (50 mL×3). The combined organic phases were 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) DCM/MeOH) to give the title compound as a pale yellow solid (0.75 g, 38.60%), HPLC: 98.30%. The compound was characterized by the following spectroscopic data: MS (ESI, pos. ion) m/z: 514.1 (M+1); 1H NMR (400 MHz, d6-DMSO) δ: 1.03 (t, J=4.6 Hz, 3H), 1.52-1.62 (m, 2H), 1.97-2.00 (m, 3H), 2.07-2.09 (m, 2H), 2.08-2.11 (m, 4H), 2.40 (q, J=4.6 Hz, 2H), 2.51-2.56 (m, 1H), 2.57-2.61 (m, 2H), 2.88-2.92 (m, 2H), 3.94 (s, 3H), 4.18 (t, J=8.6 Hz, 2H), 7.19 (s, 1H), 7.44 (t, J=10.4 Hz, 1H), 7.82 (s, 2H), 8.13 (t, J=6.8 Hz, 1H), 8.50 (s, 1H) ppm.
