实验步骤: Methoxylamine hydrochloride (0.668 g, 8.00 mmol), was added to a stirred solution of 1-(4-chlorophenyl)-2-(1H-pyrazol-1-yl)ethanone (Intermediate 90) (1.103 g, 5 mmol), at room temperature under argon. The resulting solution was stirred at room temperature overnight. The pyridine was evaporated in vacuo and the residual solid was triturated with a saturated aqueous solution of sodium hydrogencarbonate (50-100 ml). The solid was filtered, washed with water and dried to afford (Z) and (E)-1-(4-chlorophenyl)-2-(1H-pyrazol-1-yl)ethanone O-methyl oxime (1.080 g, 87%) as a dark yellow solid. The pyridine was evaporated in vacuo the residual solid was triturated with a saturated aqueous solution of sodium hydrogencarbonate (50-100 ml) The solid was filtered washed with water dried
