Procedure

N-Hydroxy-4-chloromethylbenzenecarboxyimidoyl chloride (15.27 g, 74.82 mmol) was dissolved in dichloromethane (300 ml), methyl 3-methoxyacrylate (10.43 g, 89.82 mmol) was added, and triethylamine (21 ml, 151 mmol) was slowly added dropwise. The mixture was stirred overnight at room temperature. Water was added, and the mixture was extracted with dichloromethane. The extract was washed with saturated brine and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure, and the obtained crude product was purified by silica gel chromatography (hexane:ethyl acetate=5:1) to give the title compound (9.67 g, 51%).
