Embodiment 1

[0513] [Example 1] (manufacture of ketoxime ester compound I-1)

[0514]

[0515] Ethylcarbazole (5g, 25.61mmol) and o-naphthoyl chloride (5.13g, 26.89mmol) were dissolved in 30ml of dichloromethane, stirred after cooling to 2°C in an ice-water bath, and aluminum chloride (3.41 g, 25.61 mmol). Stirring was further performed at room temperature for 3 hours. The reaction solution was poured into 200 ml of ice water, 200 ml of dichloromethane was added, and the organic layer was separated. The recovered organic layer was dried over magnesium sulfate and evaporated to give a white solid (10 g). The reaction formula is shown below.
