Procedure
While cooling externally with a mixture of ice and common salt, 21.3 g (0.1 mol) of 4-(4-chlorophenyl)-4-oxobutanoic acid were added batchwise to 100 ml of fuming nitric acid in such a way that the temperature of the mixture did not exceed 0° C. The mixture was stirred for another 1 hour at an internal temperature of between −5 and 0° C., then stirred into 1 l of ice water, after ½ hour the precipitate was collected on a filter, thoroughly washed with water until free from acid, and the crystalline product was dried in a circulating air dryer. 23.4 g (91% of theoretical) of pale yellow crystals were obtained.
