A solution of ethyl 6-(4-chlorophenyl)-2,4,6-trioxohexanoate (0.26 g) in cold concentrated sulphuric acid (3 ml) was stirred for 3 hours at 0°-5° C. then poured on to ice (10 g). The solid product was recrystallised from ethanol-water to give the title product identical (mp, IR and NMR, and thin-layer chromatography) with the product described in Example 12.
