The present invention provides processes for producing (2S,3R,4R,5S,6R)-5-fluoro-6- hydroxymethyl-2-[4-(4-methoxy-benzyl)-5-trifluoromethyl-1H-pyrazol-3-yloxy]- tetrahydro-pyran-3,4-diol or a tautomer or hydrate thereof, of high purity and in a relatively high yield suitable for use on an industrial scale. The present invention is also directed to synthetic intermediates that are useful for the preparation of (2S,3R,4R,5S,6R)-5-fluoro-6-hydroxymethyl-2-[4-(4-methoxy- benzyl)-5-trifluoromethyl-1H-pyrazol-3-yloxy]-tetrahydro-pyran-3,4-diol or a tautomer or hydrate thereof.
本发明提供了一种生产(2S,3R,4R,5S,6R)-5-氟-6-羟甲基-2-[4-(4-甲氧基苯甲基)-5-三氟甲基-1H-吡唑-3-氧基]-四氢吡喃-3,4-二醇或其互变异构体或水合物的工艺,具有较高的纯度和相对较高的产率,适用于工业规模生产。本发明还涉及合成中间体,可用于制备(2S,3R,4R,5S,6R)-5-氟-6-羟甲基-2-[4-(4-甲氧基苯甲基)-5-三氟甲基-1H-吡唑-3-氧基]-四氢吡喃-3,4-二醇或其互变异构体或水合物。
