実験手順
84 g of diketene were added over 20 minutes to a mixture of 172 g of m-bromo-aniline and 600 ml of benzene and the mixture was stirred for 5 hours at 20° C. The mixture was filtered and the precipitate was washed with benzene and isopropyl ether. The filtrate was vacuum filtered and evaporated to dryness to obtain 189 g of m-bromo-acetylacetanilide melting at 110° C.
