실험 절차

The procedure is as in Example 24 for the preparation of N-(3-dimethylamino-3-phenylpropenylidene)-N-methylmethanaminium tetrafluoroborate, starting with 4-dimethylamino-1-phenyl-3-butene-1,2-dione (9.3 g), triethyloxonium tetrafluoroborate (10.3 g) and dimethylamine (3.2 cc) in dichloromethane (140 cc). After precipitation in ethyl acetate (30 cc), N-(3-dimethylamino-3-benzoylpropenylidene)-N-methylmethanaminium tetrafluoroborate (5 g), m.p. 140° C., is obtained.
