Versuchsvorschrift

The (S)-tert-butyl 3-((R)-2-(4-(cyclopropylsulfonyl)phenyl)-3-((5-fluorothiazol-2-yl)amino)-3-oxopropyl)pyrrolidine-1-carboxylate (2.57 g, 4.91 mmol) obtained in Example 1 was dissolved in hydrochloric acid (4 M ethyl acetate solution, 10 mL), and the obtained mixture was then stirred for 10 minutes. Thereafter, the reaction solution was concentrated in vacuo, and the obtained residue was then dissolved in chloroform. The obtained solution was washed with a saturated aqueous solution of sodium hydrogen carbonate, was then dried over sodium sulfate, and was then concentrated in vacuo, so as to obtain (R)-2-(4-(cyclopropylsulfonyl)phenyl)-N-(5-fluorothiazol-2-yl)-3-((S)-pyrrolidin-3-yl)propanamide (2.26 g, quant) in the form of a white solid.
