Procedure

A solution of (3S)-1-(2-chloropyrimidin-4-yl)-3-cyclopropyl-2-oxopyrrolidine-3-carbonitrile (11.5 g) obtained in Step E of Example 103, 2-(4-amino-1H-pyrazol-1-yl)-2-methylpropan-1-ol (7.1 g) obtained in Step H of Example 103 and acetic acid (2.6 mL) in ethanol (200 mL) was stirred in a sealed tube reactor at 150° C. for 1 hr, and the solvent was evaporated under reduced pressure. The reaction mixture was neutralized with saturated aqueous sodium bicarbonate, and 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 (hexane/ethyl acetate), and recrystallized (diisopropyl ether/ethyl acetate) to give the title compound (6.9 g).
