Procedure

To 0.1 Mol of 4-nitro-3-methyl-2-butenol in benzene was added 0.1 Mol of 2,4-dichlorobenzoylchloride and stirred overnight. The benzene was removed, the residue taken up in sat. sodiumbicarbonate solution and extracted with ether. The crude product was purified by column chromatography over silica gel using methylenechloride as eluting solvent. A yellowish oil was obtained.
