- An object of the present invention is to solve the drawbacks of the conventional production method, and to provide a high] three-body selectivity, a low cost and a simple process, and a simple process. It is an object of the present invention to provide a method for producing a 5-trifluoromethylperacyl derivative.
- the present inventors have proposed 5-trifluoromethyl-2,4-bis (trimethylsilinoleoxy) pyrimidine and other 2-deoxy ⁇ -D-erythropentofuranosyl chloride.
- the reaction was carried out without solvent.
- the present inventors when performing this solvent-free reaction, in order to avoid the tendency of stirring becomes difficult due to the viscosity of the reactant increases with the progress of the reaction, the solvent is the total of the reaction raw materials
- the reaction is carried out by adding a mass of not more than 4 times the mass to ensure smooth stirring and operability, and to achieve the desired product, which is the target product, 1.1- (2, -dexoxy j3—D-erythropentofurano).
- (Sil) -5-trifluoromethylperacyl derivative was obtained with high selectivity.
- the present invention has been made based on these findings of the present inventors.
- One embodiment of the method for producing a trifluorothymidine derivative of the present invention comprises the following formula (1)
- another embodiment of the method for producing a trifluorothymidine derivative of the present invention includes the following formula (1) as a first raw material:
- a solvent may be added to induce the step in the presence of the solvent.
- 5-Trifluoromethyl-2,4-bis (trimethylsilyloxy) pyrimidine used as the first raw material is easily synthesized from a known compound, 5-trifluoromethylperacil, by a known method. Yes (see, for example, TA Khawaja, et al., J. Med. Chem., 12, 543 (1969), etc.)
- the 2-deoxy-l-D-erythropentofuranosyl chloride derivative as the second raw material can also be synthesized in a few steps by a known method using 2-dexoxylipose, which can be easily handled, as a starting material.
- 2-dexoxylipose which can be easily handled, as a starting material.
- Pentofuranosyl chloride can be synthesized using 2-dexoxylipose as a starting material according to JJ Fox, et al., J. Am. Chem. Soc, 83, 4066 (1961).
- the molar ratio of the first and second raw materials used in the present invention is preferably in the range of 0.5 or more and 2 or less, and the upper limit of this range is more preferably 1 economically.
- the reaction between the first raw material and the second raw material in the present invention is carried out without a solvent or in the presence of a predetermined amount or less of a solvent.
- the solvent to be added is not particularly limited as long as it is an aprotic solvent used in the present invention. Examples of such non-protonic solvents include aromatic solvents such as 1,2,4-trichlorobenzene, 0-dichlorobenzene, cyclobenzene, anisol, toluene and nitrobenzene, and diisopropylbenzene.
- Ether solvents such as ether, getyl ether, tetrahydrofuran and dioxane; ester solvents such as ethyl acetate; ketone solvents such as acetone, methyl ketone and methyl isobutyl ketone; Gen-based aliphatic solvents can be mentioned as preferred.
- a solvent can be formed using at least one of these.

If the amount of the solvent is more than 4 times, 13 selectivity will be reduced and the object of the present invention cannot be achieved.
- a method for adding the solvent to the reaction system a method in which at least one of the first and second raw materials is mixed in advance and added can be used. Further, a method in which the first and second raw materials are mixed immediately or after the first and second raw materials are mixed and added as the reaction proceeds, can also be used.

- Reaction temperatures range from 11 ° C to the boiling temperature of the solvent, preferably from room temperature to 70 ° C. If the temperature is lower than room temperature, the reaction proceeds slowly, and if the temperature exceeds 70 ° C, decomposition of the raw materials and products and side reactions occur. The reaction is usually completed in 0.5 to 48 hours.
- Example 2 it is a surprising fact that the selectivity and the yield of ⁇ 3 isomer are improved in the presence of a solvent or a small amount of a solvent, despite the equimolar reaction.
