실험 절차

(E)-(3-Chloro-4-methanesulfonyl-phenyl)-cyclopentyloxyimino-acetic acid (prepared as in Example 1, 96 mg, 0.28 mmol), N,N-diisopropylethylamine (145 μL, 0.83 mmol) and 2-amino-thiazole-5-carboxylic acid amide (prepared as in Example 12, 48 mg, 0.34 mmol) were combined in acetonitrile (1.4 mL) and cooled to 0° C. O-(7-Azabenzotriazole-1-yl)-N,N,N′N′-tetramethyluronium hexafluorophosphate (106 mg, 0.28 mmol) was added and the cooling bath was removed. After stirring 16 h, the reaction mixture was treated with saturated aqueous sodium bicarbonate solution (30 mL) and extracted with 10% methanol/chloroform (3×35 mL). The combined organic phases were dried over magnesium sulfate and evaporated in vacuo. The residue was purified by flash column chromatography (Merck silica gel 60, 40-63 μm; 2% methanol/chloroform) to afford (E)-2-[2-(3-chloro-4-methanesulfonyl-phenyl)-2-cyclopentyloxyimino-acetylamino]-thiazole-5-carboxylic acid amide (16 mg, 12%) as a white solid after lyophilization from aqueous dioxane: LC-MS (ESI) m/e calcd for C18H19ClN4O5S2 [M+] 470.05, found 471 [M+H+]: H1-NMR (400 MHz, CD3OD) δ ppm 1.66 (m, 4 H, 2×CH2), 1.92 (m, 4 H, 2×CH2), 3.34 (s, 3 H, SO2CH3), 5.04 (m, 1 H, OCH), 7.66 (dd, Jo=8.2, Jm=1.6 Hz, 1 H, Ar), 7.78 (d, Jm=1.6 Hz, 1 H, Ar), 8.05 (s, 1H, Ar), 8.17 (d, Jo=8.2 Hz, 1 H, Ar).
