Triethylamine → 4-Bromo-N-(2-(phenylamino)phenyl)benzamide

Participants

Reaction Steps

To a solution of 4-bromo-benzoyl chloride (11 g, 50 mmol) in anhydrous dichloromethane (DCM) (100 ml), was added N-phenylbenzene-1,2-diamine (10.2 g, 55 mmol), then triethylamine (TEA) (17 ml, 122 mmol) slowly. The whole was stirred at room temperature (RT) overnight. Filtration gave a white solid 1 (6.5 g). The filtrate was worked up with water (300 ml), then extracted with DCM (300 ml) three times. The organic phase was collected and dried over MgSO4, concentrated and recrystallized in DCM/hexanes to give another portion of white solid 1 (10.6 g). Total amount of product 1 is 17.1 g, in 93% yield.
