Versuchsvorschrift

6-amino-4-(3-chloro-4-fluorophenylamino)-7-methoxy-quinazoline (1.0 eq.) and triethylamine (1.5 eq.) were dissolved in DMF (10 ml), and the mixture was stirred at 0° C. for 30 min. A solution of diethyl (2-chloro-1-fluoro-2-oxoethyl)phosphonate (1.5 eq.) in DMF (5 ml) was added dropwise slowly into the mixture mentioned above, and stirred overnight at room temperature. After the reaction finished, the mixture was quenched with saturated NaHCO3, extracted with EtOAc, and the organic phase was dried over anhydrous sodium sulfate, concentrated to dryness under reduced pressure, then the crude product was purified by column chromatography (mobile phase 40:1 DCM/MeOH) and a light yellow solid of diethyl (2-((4-((3-chloro-4-fluorophenyl)amino)-7-methoxy-quinazolin-6-yl)amino)-1-fluoro-2-oxoethyl)phosphonate was given. (50% yield).
