Reaction Steps

Tert-butyl chloroacetate (1.43 ml, 10 mmol) was added dropwise to a mixture of 4-(3-chloro-2-fluoroanilino)-7-methoxy-6-[(piperidin-4-yl)oxy]quinazoline (4.02 g, 10 mmol), potassium iodide (1.66 g, 10 mmol) and potassium carbonate (1.66 g, 12 mmol) in dimethylacetamide (50 ml). The mixture was heated at 70° C. for one hour. After evaporation of the solvents under vacuum, the residue was triturated in water. The resulting solid was filtered, washed with water and purified by chromatography on silica gel (eluant: 2% 7N methanolic ammonia in dichloromethane) to give tert-butyl[4-({4-(3-chloro-2-fluoroanilino)-7-methoxyquinazolin-6-yl}oxy)piperidin-1-yl]acetate as a white solid (3.0 g, 60%).
