Reaction Steps

A stirred mixture of 2-[1-(4-chlorobenzyl)-1H-indol-3-yl]-N-(3-methyl-isothiazol-5-yl)-2-oxo-acetamide (0.102 g, 0.25 mmol), hydroxylamine hydrochloride (17 mg, 0.25 mmol), and sodium acetate (0.1 g, 1.2 mmol) in EtOH (3 mL) and THF (3 mL) was heated to reflux for 3 days. After being cooled to rt, the reaction mixture was poured into ice-H2O (20 mL). The precipitated product 2-[1-(4-Chloro-benzyl)-1H-indol-3-yl]-2-hydroxyimino-N-(3-methyl-isothiazol-5-yl)-acetamide was collected by filtration, washed with H2O, and dried in vacuo (95 mg, 90%). 1H NMR (DMSO-d6) δ 2.3 (s, 3H), 5.6 (s, 2H), 6.9 (s, 1H), 7.0-7.5 (m, 7H), 8.1 (d, 1H, J=7), 8.65 (s, 1H). ESMS calcd for (C21H17ClN4O2S): 424.1; found 425.1 (M+H)+.
