Diverse trifluoromethyl-substituted compounds were synthesized by deoxofluorination of cinnamic and (hetero)aromatic carboxylic acids with sulfur tetrafluoride. The obtained products were used as starting materials in the preparation of novel fluorinated amino acids, anilines, and aliphatic amines - valuable building blocks for medicinal chemistry and agrochemistry.

A procedure is described for the stepwise introduction of substituents (hydrogen included) into the imidazole ring by FGI of the bromine atoms in 1-protected 2,4,5-tribromoimidazoles in the order 2 → 5 → 4 using halogen-metal exchange techniques.
To develop an antibiotic having a novel mechanism of action, the present inventors have searched for a compound that has weak cytotoxicity, the physical property of high solubility in water, the effect of inhibiting both DNA gyrase GyrB and topoisomerase IV ParE subunits, and sufficient antibacterial activity. As a result, the present inventors have completed the present invention by finding that a compound of the present invention represented by the general formula (1), a pharmacologically acceptable salt thereof, and a prodrug thereof have desirable properties. The present invention provides a pharmaceutical composition (particularly, a preventive or therapeutic composition for infectious disease) comprising a compound represented by the formula (1), a pharmacologically acceptable salt thereof, or a prodrug thereof as an active ingredient.
