実験手順
To a solution of 4-bromo-3-chloro-benzoic acid (commercially available) (5.0 g) in dichloromethane (30 ml) was added N-(−3-dimethylaminopropyl)-N′-ethylcarbodiimid hydrochloride (5.29 g), N,N-dimethylaminopyridine (1.19 g) and trimethylsilylmethylamine (2.85 ml). The reaction mixture was stirred at ambient temperature for 5 hours. Water and dichloromethane was added to the reaction mixture. The phases were separated and the organic phase was washed with brine, dried over sodium sulfate and filtered through silica gel. The reaction mixture was concentrated to give 4-bromo-3-chloro-N-trimethylsilanylmethyl-benzamide (4.87 g). 1H-NMR (400 MHz, CDCl3): 7.68 (d, 1H), 7.55 (s, 1H), 7.33 (d, 1H), 5.85 (s, 1H), 2.84 (d, 2H), 0.00 (s, 9H) ppm.
