Procedure

A suspension of 4-chloro-7-methoxyquinazolin-6-yl acetate (4.31 g), 3-ethynyl-4-fluoroaniline (2.77 g) and isopropanol (65 mL) was stirred at 83° C. overnight. The reaction mixture was cooled to room temperature and filtered, the residue was washed with 100 mL of isopropanol and dried to afford the desired compound as a solid (5.29 g, 88.30%).
