実験手順

To methyl 3-methyl-2-(3-(4-(2-oxo-2-(3-(trifluoromethyl)phenylamino)acetamido) phenyl)isoxazole-5-carboxamido)butanoate (100 mg) in THF (2 ml) 1 M aqueous solution of Lithium hydroxide monohydrate (0.375 ml) was added and reaction mixture was stirred at RT for 6 hours. The reaction mixture was acidified with dilute HCl and extracted with EtOAc. Organic layer was collected and dried over Na2SO4 and concentrated to obtain off white solid, which was crystallized from EtOAc to yield 22 mg (22%) of the title compound as white solid. MS (ES+): m/z 519 (M+1); 1HNMR (DMSO-d6; 300 MHz): δ 11.24 (s, 1H), 11.13 (s, 1H), 9.01 (d, 1H), 8.35 (dd, 1H), 8.16 (dd, 1H), 8.06 (d, 2H), 7.96 (d, 2H), 7.73 (s, 1H), 7.64 (m, 1H), 7.54 (dd, 1H), 4.28 (m, 1H), 2.23 (m, 1H), 0.98 (d, 6H).
