실험 절차

(S)-2-(tert-butoxycarbonylamino)-3-(3-chloro-4-hydroxyphenyl)propanoic acid (3.86 g, 12.2 mmol, Eq: 1.00) was dissolved in DMF (50 mL). HATU (9.3 g, 24.4 mmol, Eq: 2.00), 1-amino-1-cyclopropanecarbonitrile hydrochloride (1.74 g, 14.7 mmol, Eq: 1.20) and Hunig's Base (3.16 g, 4.27 mL, 24.4 mmol, Eq: 2.00) were added to the obtained suspension. The reaction mixture was stirred at 25° C. for 24 h. The reaction mixture was poured into aqueous 0.1M HCl (300 mL), extracted with dichloromethane (3×125 mL), dried over Na2SO4, filtered and evaporated. The crude material was purified by flash chromatography (silica gel, 80 g, 0% to 65% AcOEt in n-heptane) to yield a white solid (3.13 g; 67%). m/z=378.1 [M−H]−.
