Reaction Steps

To a suspension of 2-chloromethyl-6,7-methylenedioxy-4-(3,4-methylenedioxyphenyl)quinazoline-3-oxide (192 mg, 0.53 mmol), in dry DMF (3 mL), was added imidazole (142 mg, 2.1 mmol). The mixture was stirred at 85° C. for 1.5 h and left at rt for 15 h. DMF was removed and the mixture was poured into ice-water. The precipitated solid was extracted with EtOAc. The organic layer was washed with water, brine and dried over anhydrous MgSO4. It was filtered and the solvent was removed to yield the title compound as off white solid (100 mg); mp 212-217° C. 1H NMR (CDCl3) 7.76 (s, 1H), 7.00-7.21 (m, 5H), 6.80 (s 1H), 6.13 (s, 2H), 6.08 (s, 2H), 5.63 (s, 2H).
