実験手順
A mixture of the above pentanoic acid (S)-4,4-difluoro-5-phenyl-2-((S)-2,2,2-trifluoro-1-(4-fluorophenyl)ethylamino)pentanoic acid, (1 mmol), 1-aminocyclopropanecarbonitrile hydrochloride (1.2 mmol), HATU (1.2 mmol) and NMM (4.0 mmol), in DMF, was stirred at RT for 2 hr. Saturated ammonium chloride and ethyl acetate were then added, and the reaction was stirred an additional 20 min at RT, after which product was extracted with ethyl acetate, purified with flash column (30-35% ethyl acetate-hexane), and crystallized with DCM-hexane to give (S)—N-(1-cyanocyclopropyl)-4,4-difluoro-5-phenyl-2-((S)-2,2,2-trifluoro-1-(4-fluorophenyl)ethylamino)pentanamide as a white crystal. 1H-NMR (CDCl3) δ 8.9 (1H), 7.2-7.5 (9H, m), 4.33 (1H, m), 3.2-3.5 (3H), 2.0-2.6 (2H), 1.6-1.8 (2H), 0.75 (1H), 0.58 (1H). 19F-NMR (CDCl3) δ−113 ppm. LC/EIMS (m/z): 470 (M+Na)+.
