実験手順

A solution of 2-fluoro-phenylhydrazine hydrochloride (0.15 g, 0.91 mmol) and triethylamine (0.13 mL, 0.91 mmol) in dimethylacetaimde (1 mL) was stirred 0.5 h at room temperature. N-cyano-N′-(4-(3-diethylamino-propoxy)-3,5-dimethoxy-phenyl)-O-phenylisourea (0.30 g as a mixture with triethylamine-trifluoroacetic acid salt, 0.45 mmol) in dimethylacetamide (1 mL) was added and the reaction was stirred at 120° C. for 20 h. The precipitate was removed and the filtrate was washed with ether. The remaining aqueous phase was evaporated and was purified by semi-preparative HPLC to provide the title compound (0.01 g, 4% yield) as a yellow lyophilate.
