The Uses of Trifluorothymine
Trifluorothymine is an antitumor and antiviral agent. Trifluorothymine was found in patientsтАЩ urine as a metabolite of Trifluorothymidine as cancer treatment.
What are the applications of Application
Trifluorothymine (5-(Trifluoromethyl)uracil) is an application medicine intermediate widely. It may be used for the synthesis of the cancer therapy drug trifluridine and also can be used for the preparation of the 2, 4-dichloro-5-trifluoromethyluracil.
Synthesis
Uracil and sodium triflate can be used as raw materials to synthesize Trifluorothymine. This reaction uses a mixed solvent of methylene chloride and water as the reaction solvent and tert-butyl hydroperoxide as the catalyst.
