실험 절차
Trifluoroacetic acid (3 ml) was added to N-[(R)-1-[3-(1-tert-butoxycarbonyl-3-azetidinyl)propanoyl]-3-piperidylcarbonyl]-3(S)-ethynyl-β-alanine (1.11 g, 2.55 mmol). The reaction mixture was stirred for 1 hour at room temperature. Solvent was evaporated in vacuo. The residue was purified by HPLC to give N-[(R)-1-[3-(3-azetidinyl)propanoyl]-3-piperidylcarbonyl]-3(S)-ethynyl-β-alanine trifluoroacetate (270 mg, 23.6%).
