Versuchsvorschrift
A mixture of 9.61 g of 3-p-chlorobenzoyl phenyl acetonitrile, 75 cc of water, 75 cc of acetic acid and 75 cc of sulfuric acid was refluxed with stirring for 21/2 hours and then cooled and iced for 1 hour. The mixture was vacuum filtered and the precipitate was empasted with water and taken up in 50 cc of a 10% aqueous sodium carbonate solution. The solution was filtered and the filter was washed with water. The pH of the filtrate was adjusted to 5-6 by addition of acetic acid and after being iced for 30 minutes, the mixture was vacuum filtered. The recovered precipitate was washed with water and dried under reduced pressure. The residue was dissolved in 50 cc of refluxing toluene and the solution was treated with activated carbon and filtered. The filter was washed with boiling toluene. The filtrate was cooled and iced for 1 hour and then vacuum filtered. The recovered precipitate was empasted with iced toluene and dried under reduced pressure to obtain 8.37 g of 3-p-chlorobenzoyl phenyl-acetic acid melting at 148° C.
