PROCEDURE
实验过程
A slurry of racemic cis-1-(6-(5-(2,6-difluorophenyl)-1-(tetrahydro-2H-pyran-2-yl)-1H-indazol-3-yl)pyrazin-2-yl)piperidine-3,4-diol (0.100 g, 0.197 mmol) in 3 mL 5-6 N HCl in IPA (acros organics) was sealed and the slurry was heated to 70° C. After 1.5 h, the reaction was cooled and concentrated in vacuo. This material was dissolved in DMSO and purified by shimadzu RPHPLC, 15-70% ACN/H2O with 0.1% TFA; product-containing fractions were concentrated in vacuo. The material was partitioned between sat'd aq NaHCO3 and DCM, and the aq. layer was extracted 3×10% MeOH/DCM. The combined organics were dried over anhydrous Na2SO4, filtered, and concentrated in vacuo to give the title compound (0.024 g, 29% yield) as an off-white solid: MS (ESI, pos. ion) m/z: 424 (M+1).
