Improved Arene Fluorination Methodology for I(III) Salts
摘要:
The use of low polarity aromatic solvents (benzene or toluene) and/or the removal of inorganic salts results in dramatically improved yields of fluorinated arenes from diaryliodonium salts. This methodology is shown to "scale down" to the conditions used typically for radiotracer synthesis.
A Compound represented by the following general formula (1), salts thereof or hydrates of the foregoing is a novel compound useful for treatment and/or prevention of diseases associated with thrombus formation, and which is safer with suitable physicochemical stability.
