It is reported that the procedure of v. Braun and Steindorff, Ber. 38, 2338 (1905), is a more satisfactory method of eliminating benzonitrile from the crude product. The distillate containing the alkylene bromide, benzonitrile, and phosphorus oxybromide is poured carefully into 90-100 cc. of water, with cooling and shaking. The resulting mixture is refluxed for eight to ten hours, with the occasional addition of 3-4 cc. of alcohol to decrease resinification. The product is then removed by steam distillation, washed with sodium carbonate solution, dried, and dis-... 

The variety of the acetacetic ester syntheses is still further increased by the fact that two molecules of the ester, by reaction with aldehydes or alkylene bromides, may be united with one another by the most various bivalent radicals.
