Reaction Steps
A mixture of 4-[(4-fluoro-2-methyl-1H-indol-5-yl)oxy]-7-hydroxy-6-methoxyquinazoline (250 mg, 0.74 mmol), 1-acetyl-4-(2-chloroethyl)piperazine (144 mg, 0.81 mmol) and potassium carbonate (112 mg, 0.81 mmol) in N-methylpyrrolidinone (6 ml) was heated at 90° C. for 2 hours. The mixture was cooled and water added. After 30 minutes the solid was filtered off and dried under vacuum. The residue was purified by column chromatography eluting with methylene chloride/methanol (saturated with ammonia) (96/4) to give 7-[2-(4-acetylpiperazin-1-yl)ethoxy]-4-[(4-fluoro-2-methyl-1H-indol-5-yl)oxy]-6-methoxyquinazoline (310 mg, 58%) as a white solid.
