Reaction Steps

To a solution of 4-phenylbenzoic acid (5.46 g, 27.6 mmol) in methylene chloride (66 mL) was added 2 drops of DMF and oxalyl chloride (2.80 mL, 30.3 mmol). The reaction mixture was stirred overnight and added to a stirred solution of ice and ammonium hydroxide. The resulting precipitate was filtered, washed with methylene chloride, and triturated with water. The product was collected by filtration and dried in vacuo to yield 4-phenylbenzamide (3.88 g, 71%).
