Procedure
To a solution of 6-amino-4-[(3-bromophenyl)amino]quinazoline (316 mg, 1.0 mmol) in THF (6 mL) stirred under N2 at 0° C. was added trans-crotonyl chloride. A yellow solid formed upon addition. The solid was collected by Buchner filtration after 2.5 hours and sonicated with EtOAc to give the title compound (216 mg, 52%), mp 279-281° C.
