To a solution of 1-trichloromethyl-3-methyl-2-butenyl acetoacetate (0.575 g, 2 mmole) and triethylamine (0.404 g, 4 mmole) in 10 ml of acetonitrile was added 1 g of polymer-bound sulfonyl azide (prepared by the method of Roush, et al., loc. cit.). The mixture was stirred overnight at room temperature and filtered. The filter cake was washed with ether, and the slurry was filtered. Solvent was removed by evaporation from the combined filtrates to give 1-trichloromethyl-3-methyl-2-butenyl 2-diazoacetoacetate (0.60 g, 96% yield).
