Reaction Steps

To a solution of (3S)-1-(2-((1-(1-amino-2-methylpropan-2-yl)-1H-pyrazol-4-yl)amino)pyrimidin-4-yl)-3-cyclopropyl-2-oxopyrrolidine-3-carbonitrile dihydrochloride (100 mg) obtained in Example 115 in tetrahydrofuran (5 mL) were added successively dropwise triethylamine (0.15 mL) and methoxyacetyl chloride (26 mg) at 0° C. under nitrogen atmosphere, and the mixture was stirred at room temperature for 5 hr. To the reaction mixture was added water, and the mixture was extracted with ethyl acetate. The obtained organic layer was washed with saturated brine, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/methanol). To a solution of the residue (89 mg) in ethanol (5.0 mL) was added 1 M hydrochloric acid (0.20 mL), and the mixture was stirred at room temperature for 5 min. The solvent was evaporated under reduced pressure, and the residue was recrystallized (diisopropyl ether/ethyl acetate) to give the title compound (81 mg).
