실험 절차

To a suspension of (2R)-N-{3-[5-(ethoxyiminomethyl)(1H-indazol-3-yl)]phenyl}-2-hydroxy-2-phenylacetamide hydrochloride (0.500 g, 1.11 mmol) in methanol (10 mL) were added 3 equivalents of N-amino-2-(dimethylamino)acetamide (0.390 g, 3.33 mmol) and 2.5 equivalents of sodium methoxide in methanol (0.635 mL, 4.3 M). After stirring at room temperature for 1 h, the reaction mixture was heated to 95° C. for 48 hours. The reaction was then quenched with water, the pH adjusted to neutral and the crude product extracted with ethyl acetate. The title compound was purified by preparative HPLC (0.050 g, 9% yield): 1H NMR (CD3OD) δ 8.72 (s, 1H), 8.23 (s, 1H), 8.08 (d, 1H), 7.89 (d, 2H), 7.68 (d, 1H), 7.58 (d, 2H), 7.51 (t, 1H), 7.40–7.32 (m, 3H), 5.21 (s, 1H), 3.71 (s, 2H), 2.37 (s, 6H); ES-MS (m/z) 468 [M+H]+.
