반응 단계
Step AI (1): To a solution of 2-bromo-5-methylbenzoic acid (1000.0 mg, 4.65 mmol) in DMF (100 mL) were added N,O-dimethylhydroxylamine hydrochloride (454 mg, 4.65 mmol), EDC (891 mg, 4.65 mmol), and HOBT (628 mg, 4.65 mmol). The reaction mixture was stirred at rt for 2.5 days. The reaction mixture was diluted with water and extracted with EtOAc. The combined organic phases were dried over Na2SO4, filtered and concentrated in vacuum. The residue was purified by silica gel chromatography to give 2-bromo-N-methoxy-N,5-dimethylbenzamide (656 mg, 55%) as a colorless oil. LC-MS (M+H)+=258.21.
