実験手順
(S)-3-[2-(3-Hydroxypyrrolidin-1-yl)acetyl]amino-1-(tert-butoxycarbonyl)pyrrolidine (531 mg) prepared in Step A mentioned above was added with a 30% solution of trifluoroacetic acid in dichloromethane (8 ml), and the mixture was stirred at room temperature for 2 hours. The volatile components were evaporated under reduced pressure to obtain the title compound as trifluoroacetate (900 mg).
