실험 절차

To a solution of 3-iodoaniline (1.5 g, 6.85 mmol) and triethylamine (1.34 mL, 9.59 mmol) in dichloromethane (28 mL) at 0° C. was added dropwise 4-bromobutyryl chloride (0.99 mL, 8.56 mmol). The reaction mixture was then stirred at room temperature overnight. The organic extract was washed with an aqueous 1M HCl solution, aqueous 1M NaOH solution and brine, dried (Na2SO4), filtered, concentrated under vacuum. The crude residue was purified by silica gel column chromatography using a gradient of EtOAc (0-15%) in cyclohexane to yield a sticky solid. Trituration in a mixture of cyclohexane and ether and then filtration give the title compound as a solid (1.61 g, 64%).
