A mixture of decahydroisoquinoline (200 mg, 1.44 mmol, 1 eq), N-(3-chloro-4-fluorophenyl)-6-(3-chloropropoxy)-7-methoxyquinazolin-4-amine (570 mg, 1.44 mmol, 1 eq) and K2CO3 (238 mg, 1.70 mmol, 1.2 eq) in DMF (15 mL) was heated at 80° C. overnight and cooled to room temperature. To this, 100 mL of CH2Cl2 was added, the mixture was washed with brine (20 mL×3) and water (20 mL×2). The organic layer was dried over anhydrous Na2SO4 and concentrated in vacuo and the residue was chromatographed with a silica gel column (20:1 (v/v) CH2Cl2/MeOH) to afford the title compound as a yellow solid (350 mg, 49.00%), HPLC: 90.00%. The compound was characterized by the following spectroscopic data: MS (ESI, pos. ion) m/z: 499.2 (M+1); 1H NMR (CDCl3, 400 MHz) δ: 1.27-1.59 (12H, m), 1.80-1.82 (2H, m), 2.07-2.33 (2H, m), 2.40-2.51 (2H, m), 3.22-3.26 (2H, m), 4.22-4.24 (2H, m), 7.14-7.16 (1H, m), 7.23 (1H, s), 7.47 (1H, s), 7.65-7.69 (1H, m), 8.00-8.02 (1H, m), 8.64 (1H, s) ppm.
