Procedure

288 mg of (2S)-pyrrolidine-2-carboxylic acid {4-[3-chloro-4-(3-fluoro-benzyloxy)-phenylamino]-7-(2-methoxyethoxy)-quinazolin-6-yl}-amide as a starting material was dissolved in 10 ml of THF, and cooled to 0° C. The solution was reacted with 0.07 ml of acrylic acid, 0.17 ml of pyridine and 0.29 g of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride at 0° C. for 30 mins and at room temperature for 2 hours. The reacted solution was extracted with a mixture of chloroform and isopropanol after adding water, washed with saturated saline solution, dried over anhydrous sodium sulfate, filtered and distilled under a reduced pressure, and the resulting residue was subjected to column chromatography (eluent-ethylacetate:methanol=30:1) to obtain the title compound (52 mg, 17%).
