A solution of 2-imino-3-benzoyl-7-dimethylamino-4-(3-methoxy-4,5-methylenedioxyphenyl)-chromane (26 mg, 0.059 mmol) and triethylamine (0.1 ml) in ethanol (5 ml) was refluxed for 12 h. It was concentrated, and the residue was purified by column chromatography (silica gel, EtOAc/Hexane=1:5) to give 18 mg (72%) of the title compound. 1H NMR (CDCl3): 7.40-7.30 (m, 2H), 7.18-7.14 (m, 2H), 6.86 (d, 1H), 6.50-6.34 (m, 2H), 6.00 (d, 1H), 5.85-5.81 (m, 2H), 5.73 (d, 1H), 4.73 (s, 1H), 3.67 (s, 3H), 2.91 (s, 6H).
