실험 절차

To a solution of methyl 3-methyl-2-(5-(4-(3-(3-(trifluoromethyl)phenyl)ureido)phenyl) oxazole-2-carboxamido)butanoate (Example 1, 150 mg) in THF (3 ml) was added 1 M aqueous solution of Lithium hydroxide monohydrate (0.6 ml) and the mixture was stirred for 4 hours at RT. The reaction mixture was acidified with dilute HCl and extracted with EtOAc. The organic layer was separated, dried over Na2SO4, concentrated under reduced pressure and then crystallized in EtOAc to give the title compound. Yield: 125 mg (85%); 1H NMR (DMSO-d6, 300 MHz): δ 12.93 (bs, 1H), 9.14 (s, 1H), 9.06 (s, 1H), 8.64 (d, 1H), 8.03 (d, 1H), 7.81 (s, 1H), 7.8 (d, 2H), 7.64 (d, 2H), 7.58 (dd, 1H), 7.52 (dd, 1H), 7.34 (m, 1H), 4.28, (m, 1H), 2.26 (m, 1H), 0.95 (d, 6H); MS (ES+) m/z 491 (M+1).
