Reaction Steps
A mixture of 300 g of 3,4-dichlorocinnamic acid methyl ester, 400 g of nitromethane and 26 g of tetramethylguanidine is allowed to stir for 72 hours. The solution is diluted with ethyl ether and aqueous hydrochloric acid solution (1 N, 1 liter) is added. The organic layer is separated, dried over anhydrous magnesium sulfate, and evaporated to give 4-nitro-3-(3,4-dichlorophenyl)butanoic acid methyl ester.
