The invention discloses a synthesis method of 3, 4, 5-trifluorophenol. The synthesis method includes following steps: taking 3, 4, 5-trifluorobromobenzene as a raw material, adding a certain volume ofammonia water and cuprous complexing catalyst, allowing
The ionic liquid [bmim]Br as an alternative medium for the catalytic cleavage of aromatic C-F and C-Cl bonds

experimental part, p. 2265 - 2268 (2010/05/18)
The potential of [bmim]Br as an alternative to aprotic dipolar solvents in nickel-catalyzed hydrodehalogenation reactions is demonstrated. Hydrodechlorination of pentafluorochlorobenzene proceeds under the action of zinc in aqueous [bmim]Br. Under the above conditions aromatic C-F bonds also undergo slow cleavage. The reaction is significantly accelerated in the presence of nickel complexes with 2,2′-bipyridine or 1,10-phenanthroline. In the case of pentafluoroacetanilide highly regioselective ortho-hydrodefluorination leading to the formation of 3,4,5-trifluoroacetanilide is observed.

The present invention relates to 4-(phenylamino)-[1,4]dioxano[2,3-g]quinazoline derivatives which inhibit tyrosine kinase of epidermal growth factor receptor (EGFR), and pharmaceutically acceptable salts, hydrates and solvates thereof, and a process for preparing the same. Since 4-(phenylamino)-[1,4]dioxano[2,3-g]quinazoline derivatives of the invention have a high solubility in water and inhibit the activity of EGFR tyrosine kinase and the growth of cancer cells, they can be practically applied in the treatment of overproliferation-associated diseases such as cancer.
