1-Methylimidazole → HCID 66680548, compound

Participants

Reaction Steps

Under ice-cooling, 1.53 g (7.97 mmol) of 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride was added to a DMAc (5 mL) solution comprising 1.45 g (6.64 mmol) of [3-(furan-3-yl)phenoxy]acetic acid, 1.60 g (6.97 mmol) of methyl 2-amino-5-bromobenzoate, and 1.08 g (7.97 mmol) of 1-hydroxybenzotriazole, and the mixture was stirred at room temperature for 4 hours. Under ice-cooling, 1.63 g (19.9 mmol) of 1-methylimidazole was added, and the mixture was stirred at room temperature overnight. Water was added to the reaction mixture, and the mixture was stirred for 1 hour. The precipitates were collected by filtration and washed with water and IPE, followed by drying under reduced pressure at 50° C. for 3 hours, thereby giving 2.30 g of methyl 5-bromo-2-({[3-(furan-3-yl)phenoxy]acetyl}amino)benzoate (yield: 81%).
