실험 절차

To a suspension of 4-((3-ethynyl-4-fluorophenyl)amino)-7-methoxyquinazolin-6-ol (3.90 g), K2CO3 (4.36 g) in DMF (30 mL) was added 1-bromo-3-chloropropane (3.80 mL) at rt, the mixture was stirred at 40° C. overnight. The reaction mixture was poured into water and filtered. The filter residue was purified by a silica gel column chromatography (eluting agent: 3:1 (v/v) PE/EA) to give the title compound as a white solid (3.30 g, 68.00%).
