Versuchsvorschrift

42 g of diketene were added to a mixture of 96 g of m-aminovaleranilide in 400 ml of benzene and the mixture was stirred for 16 hours at 20° C. The benzene was decanted and the residue was added to refluxing benzene. The mixture was treated with activated carbon and filtered to obtain raw m-valeramido-acetylacetanilide melting at 90° C. Crystallization from ethyl acetate yielded 34 g of pure m-valeramido-acetylacetanilide melting at 116° C.
