Reaction Conditions

Reaction Steps

170 mg of 2-amino-N-{4-[3-chloro-4-(3-fluoro-benzyloxy)-phenylamino]-7-methoxy-quinazolin-6-yl}-acetamide as a starting material was dissolved in 5 ml of THF, and cooled to 0° C. The solution was reacted with 0.04 ml of acrylic acid, 0.06 ml of pyridine and 134 mg of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride at 0° C. for 1 hour and at room temperature for 5 hours. The reacted solution was extracted with chloroform after adding saturated sodium bicarbonate, dried over anhydrous sodium sulfate, filtered and distilled under a reduced pressure, and the resulting residue was subjected to column chromatography (eluent-ethylacetate methanol=10:1) to obtain the title compound (51 mg, 27%).
