Participants

Reaction Steps

500 mg of 4-[(3-chloro-4-fluoro-phenyl)amino]-6-{[4-(piperazin-1-yl)-1-oxo-2-buten-1-yl]amino}-7-cyclopropylmethoxy-quinazoline are dissolved in 5 ml of acetonitrile, and 0.35 ml of triethylamine followed by 0.17 ml of benzyl bromo-acetate are added dropwise at room temperature. The reaction mixture is stirred for approximately 45 minutes at room temperature and then concentrated in vacuo. The solid residue is triturated with water and filtered off. The crude product is purified by column chromatography on silica gel with methylene chloride/methanol (20:1) followed by recrystallization from ethyl acetate. Yield: 380 mg (59% of theory), Melting point: 174° C. Mass spectrum (ESI−): m/z=657, 659 [M−H]−
