Abstract

NEW MATERIAL:2-Hydroxymethyl-3,3,3-trifluoropropionic acid shown by the formula I. USE:An intermediate capable of producing simply in high yield 5- trifluoromethyldihydrouracil suitable as an intermediate for trifluorothymidine (carcinostatic agent). PREPARATION:2-Trifluoromethylacrylic acid shown by the formula II is reacted with water in the presence of an acid such as hydrochloric acid, sulfuric acid, etc., especially sulfuric acid preferably at 90-130 deg.C to give a compound shown by the formula I. The compound is reacted with urea in dimethylformamide in the presence of acetic anhydride to give 5-perfluoromethyldihydrouracil shown by the formula III, which is reacted with bromine in acetic acid and heated to give trifluorothymine. This compound is condensed with a saccharide to synthesize trifluorothymidine.

<'C-F)-[Field of therapeutic use] The 2-hydroxymethyl-3,3,3-)lifluoropropionic acid represented by the formula (1) of the present invention is anhydrous in dimethylformamide. By reacting urea in the presence of acetic acid, it can be led to 5-perfluoromethyldihydrouracil. Furthermore, it can be induced to trifluorothymine by reacting it with a sulfate in 5-perfluoromethyldihydrouracilhacetic acid and then heating. It is known that trifluorothymidine, which is a combination of trifluorothymine and a saccharide, is useful as an anticancer agent.
