A total of 55.7 grams of p-nitrobenzoyl chloride was dissolved in 225 milliliters of benzene and, while stirring, 65 grams of anhydrous aluminum chloride was added thereto over a period of 40 minutes, all of which was done under a nitrogen atmosphere. After addition was completed, the mixture was stirred for 30 minutes on a steam bath and then poured over ice. Extraction of the resulting product with methylene chloride, followed by washing the organic layer with water, drying with anhydrous magnesium sulfate and filtering, resulted in the recovery of 62.2 grams of p-nitrobenzophenone.
