Procedure

15 ml of isopropyl alcohol, 75 mg of triethylamine and 125 mg of piperonylamine were added to 140 mg of 4-chloro-6-cyanoquinazoline. The obtained mixture was heated under reflux for 5 hours and filtered to recover a precipitate. This precipitate was introduced to a silica gel column, followed by eluting with ethyl acetate to give 200 mg of the title compound.
