実験手順
Oxalyl chloride (0.34 g, 2.65 mmole) in 5 ml acetonitrile was added to 16 ml acetonitrile containing dimethylformamide (0.25 g, 3.46 mmole) cooled to 0° C. After 15 minutes, 2-(4-chlorophenyl)-1-[4-(methylsulfonyl)phenyl]-1H-imidazole-4-carboxylic acid from step 1 (1.0 g, 2.65 mmole) was added with 20 ml acetonitrile. After warming to room temperature N,0-dimethylhydroxylamine HCl (0.28 g, 2.92 mmole) and pyridine (0.42 g, 5.31 mmole) were added and the mixture was stirred at room temperature for three days. The reaction mixture was concentrated to give an oily solid. The amide was purified by silica gel chromatography: Anal. Calc'd. C19H15N3O4SCl (419.89); C, 54.35; H. 4.32; N, 10 10.01. Found: C, 53.96; H, 4.30; N, 9.68.
