Methyl 3-(4-phthalimidobutoxy)benzoate (6.60 g, 18.68 mmol) was dissolved in 50 mL of ethanol and reacted with hydrazine monohydrate (1.87 g, 37.36 mmol). Following stirring at 80° C. for 1 hour, the resulting mixture was diluted with chloroform, then washed with a saturated sodium bicarbonate solution, water, and brine, and dried with sodium sulfate. The resulting reaction solution was concentrated under reduced pressure to give a white crystal (4.81 g). The white crystal was directly used in subsequent reaction.
