Trifluorothymine Chemical Properties,Uses,Production

Chemical Properties

White to faintly yellow crystalline powder

Uses

Trifluorothymine is an antitumor and antiviral agent. Trifluorothymine was found in patientsтАЩ urine as a metabolite of Trifluorothymidine as cancer treatment.

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.
