Participants

Reaction Steps

4.12 g (0.0196 mol) of 4-chloro-6-methylthioquinazoline, 3.70 g (0.0245 mol) of piperonylamine and 3.50 g (0.0330 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 obtained residue was purified by silica gel column chromatography (ethyl acetate/n-hexane) and recrystallized from chloroform/n-hexane to give 5.32 g of the title compound as a pale-yellow crystal.
