This invention relates to a novel method for preparing ruxolitinib phosphate. Methyl 4-(1-(2-cyano-1-cyclopentylethyl)-1H-pyrazol-4-yl)-7H-pyrrolo[2,3-D]pyrimidin-7-yl)terpentanoate (compound X) is deprotected under alkaline conditions, then directly resolved without separation, alkalized to release the free ruxolitinib, and salted to obtain the ruxolitinib phosphate. The obtained ruxolitinib phosphate has an HPLC purity >99.90%, and the ruxolitinib phosphate isomer has a purity >99.50%. The preparation method of this invention has the advantages of simple operation, controllable impurities, low cost, and suitability for industrial production.

Improved processes for preparing enantiomerically enriched intermediates for the synthesis of ruxolitinib and deuterated forms of ruxolitinib and deuterated analogs of ruxolitinib of Formula I:wherein, Y1 is hydrogen or deuterium; each Y2 is the same and is hydrogen or deuterium; and each Y3 is the same and is hydrogen or deuterium are disclosed. Certain aspects are also directed to deuterated intermediates useful in the synthesis of deuterated forms of ruxolitinib. Certain aspects are also directed to reaction mixtures for preparing enantiomerically enriched intermediates useful in the synthesis of ruxolitinib and deuterated forms of ruxolitinib.
