3,4-Dichloroaniline → N-(3,4-dichlorophenyl)-2-(3-hydroxyphenyl)acetamide

Participants

Reaction Steps

To a solution of 3-hydroxyphenyl acetic acid (5.0 g, 0.03 mol) in DMF (50 ml) was added 1-hydroxybenzotriazole hydrate (4.86 g, 0.03 mol) and 1-[3-(dimethylamino)propyl]-3-ethylcarbodiimide hydrochloride (6.9 g, 0.036 mol). To the flask was added 3,4-dichloroaniline (4.86 g, 0.03 mol). The reaction was allowed to stir overnight. Solvent was removed and the reaction was diluted with ethyl acetate. The reaction mixture was washed with 1N HCl, 10% sodium carbonate solution, and brine. The organic layer was dried over MgSO4, filtered and concentrated to provide the title compound (5.5 g, 62% yield): ES-MS (m/z) 296 [M+H]+.
