To 0.1 Mol of 4-nitro-3-methyl-2-butenol in benzene was added 0.1 Mol of 3,5-dinitrobenzoylchloride and stirred overnight. The benzene was evaporated and the residue was stirred in sat. sodiumbicarbonate solution for 1 hour. The solid product was filtered and recrystallized first from alcohol water and then from ethylacetate/hexane. The product was obtained as a yellow crystalline material, m.p. 111°-113°.
