To a stirred solution of 7-amino-4-[(3-methylphenyl)amino]quinazoline (123 mg, 0.49 mmol), acrylic acid (0.04 mL, 0.58 mmol), triethylamine (0.15 mL, 1.1 mmol) in DMF (1.5 mL) at 0° C. was added 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (123 mg, 0.64 mmol). The resulting light yellow mixture was stirred at 25° C. for 20 hours and quenched with water. The solid was collected and purified by sonication with a mixture of CH2Cl2/EtOAc/MeOH to give the desired product as a yellow solid (75 mg, 49%), mp 269.7-270° C.
