Reaction Steps
2.72 g (0.0100 mol) of 2-ethoxycarbonyl-4,6-dichloroquinazoline, 1.75 g (0.0116 mol) of piperonylamine and 1.60 g (0.0151 mol) of sodium carbonate were mixed with 100 ml of isopropyl alcohol. The obtained mixture was heated under reflux for 24 hours and distilled under a reduced pressure to remove the solvent. The residue was purified by silica gel column chromatography and recrystallized from chloroform/n-hexane to give 3.56 g of the title compound as a colorless needle.
