実験手順

A mixture of compound 63 (0.91 g) and p-toluenesulfonic acid (1.3 g) was heated in acetone and water at 50° C. until starting material was consumed. After evaporation of acetone, the residue was extracted between EtOAc and saturated sodium bicarbonate. The organic phase was dried over sodium sulfate and evaporated to dryness. The crude product was purified by column chromatography with 70% to 80% EtOAc/Hex to give (S)-3-(3,4-difluorophenyl)-N-(3,3-dimethyl-1-(methylamino)-1-oxobutan-2-yl)-5-oxo-4,5,6,7-tetrahydro-1H-indazole-1-carboxamide (0.75 g, 91% yield), which was reduced with sodium borohydride (1.0 equiv.) in MeOH to give compound 67 as a mixture of two diastereomers after purification with a preparative LC-MS. LCMS (+ESI) m/z=421.2 [M+H]+.
