Paragraph 0043; 0044, (2017/07/19)
The invention provides a synthesis method of sofosbuvir. The synthesis method of the sofosbuvir comprises the following steps: performing mitsunobu reaction on ((2R,3R,4R)-3-benzoyloxy)-4-fluorine-5-hydroxyl-4-methyltetrahydrofuran-2-yl)methyl benzoate to produce sulfonate to obtain a compound 1; abutting the compound 1 and N-benzoylcytosine to produce a compound 2. The method adopts mitsunobu reaction to avoid production of an isomer, and the isomer is reduced to 5 percent or below; according to the method, sulfonate and N-benzoylcytosine are abutted, so the use ofa stannic chloride raw material is avoided; furthermore, the yield is high and few solid waste is generated during aftertreatment, so that the method is suitable for large-scale industrialized production.
