Reaction Steps

0.74 g (2.4 mmol) of the 2-benzyloxymethyl-4-chloro-6-methoxyquinazoline prepared in Example 246, 0.55 g (3.6 mmol) of piperonylamine and 0.50 g of sodium carbonate were mixed with 20 ml of isopropyl alcohol. The obtained mixture was heated under reflux. After 6 hours, the reaction mixture was distilled under a reduced pressure to remove the solvent and the residue was purified by silica gel column chromatography (ethyl acetate/n-hexane) and recrystallized from chloroform/n-hexane to give 1.01 g of the title compound as a yellow crystal.
