Versuchsvorschrift

A solution of 356 g of 4-nitro-3-phenylbutanoic acid methyl ester, 138 g of methyl acrylate, and 25 ml of Triton B in 500 ml of t-butanol is allowed to stir at room temperature for 94 hours. Excess aqueous hydrochloric acid (1 N) is added and the solution is diluted with diethyl ether. The organic layer is separated, dried over anhydrous magnesium sulfate and evaporated to give 4-nitro-3-phenylheptanedioic acid dimethyl ester.
