O-Methyltyramine → 4-bromo-N-[2-(3-methoxyphenyl)ethyl]benzamide

Participants

Reaction Steps

29.2 ml of 2-(4-methoxyphenyl)-ethylamine and 34.2 ml of diisopropylethylamine are added dropwise in succession at 0° C. to a solution of 43.9 g of 4-bromobenzoyl chloride in 500 ml of methylene chloride. The reaction mixture is left to warm to room temperature and stirred, subsequently diluted with methylene chloride and treated with saturated sodium hydrogen carbonate solution. The organic phase is washed with saturated sodium hydrogen carbonate solution and then saturated sodium chloride solution, dried and concentrated. There are obtained 66.1 g of 4-bromo-N-[2-(3-methoxy-phenyl)-ethyl]-benzamide, MS: m/e 333 (M+, 1 Br).
