Reaction Steps

A mixture of 4-((3-ethynyl-4-fluorophenyl)amino)-7-methoxyquinazolin-6-ol (220 mg, 0.71 mmol, 1 eq), 5-(3-chloropropyl)octahydrofuro[3,4-c]pyridine (174 mg, 0.44 mmol, 1.2 eq) and K2CO3 (197 mg, 1.42 mmol, 2 eq) in DMF (10 mL) was stirred at 80° C. overnight, and cooled to room temperature. To this, CH2Cl2 (50 mL) was added. The mixture was washed with brine (20 mL×3) and water (20 mL×2), then dried over anhydrous Na2SO4 and filtered. The filtrate was concentrated in vacuo and the residue was purified by a silica gel column chromatography (eluting agent: 20:1 (v/v) CH2Cl2/CH3OH) to give the title compound as a yellow solid (110 mg, 32.50%), HPLC: 97.45%. The compound was characterized by the following spectroscopic data: MS (ESI, pos. ion) m/z: 477.2 (M+1); 1H NMR (400 MHz, CDCl3) δ: 1.76-1.77 (2H, m), 2.24-2.48 (3H, m), 2.50-2.64 (2H, m), 2.68-2.71 (3H, m), 2.73-2.75 (2H, m), 2.96-3.03 (3H, m), 3.07-3.12 (2H, m), 3.61-3.90 (2H, m), 4.07 (1H, s), 4.24-4.27 (2H, m), 7.06-7.10 (1H, m), 7.16 (1H, s), 7.76-7.82 (1H, m), 7.82 (1H, s), 8.09-8.11 (1H, m), 8.59 (1H, s) ppm.
