Versuchsvorschrift

4-(3-chloro-2-fluoroanilino)-7-methoxy-6-[(2S)-pyrrolidin-2-ylmethoxy]quinazoline hydrochloride (1.1 g, 2.5 mmol; prepared as described in Example 31-starting materials) was dissolved in a mixture methylene chloride (20 ml) and diisopropylethylamine (1.0 ml) under a nitrogen atmosphere. The solution was cooled in an ice/water bath to 4° C. and chloroacetyl chloride (0.2 ml, 2.63 mmole) was added. The reaction mixture was stirred cold for two 25 hours and then partitioned between methylene chloride and saturated aqueous NaHCO3. The organic layer was separated, washed with brine, dried over Na2SO4, filtered and evaporated to give 4-(3-chloro-2-fluoroanilino)-7-methoxy-6-{[(2S)-1-(chloroacetyl)pyrrolidin-2-yl]methoxy}quinazoline (1.14 g, 94.9%); Mass Spectrum: (M+H)+ 479.
