Versuchsvorschrift

To a solution of (3S)-3-cyclopropyl-1-(2-((1-(1-hydroxy-2-methylpropan-2-yl)-1H-pyrazol-4-yl)amino)pyrimidin-4-yl)-2-oxopyrrolidine-3-carbonitrile (400 mg) obtained in Step I of Example 103 and cobalt(II) chloride hexahydrate (1.0 g) in methanol (6.0 mL) was added sodium borohydride (400 mg), and the mixture was stirred at room temperature for 4 hr. To the reaction mixture was added saturated aqueous sodium hydrogen carbonate solution in an ice bath, and the mixture was extracted with ethyl acetate. The obtained organic layer was washed with saturated brine, and dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/methanol) to give the title compound (84 mg).
