実験手順
To 5.0 g of dimethyl-1,3-dioxolane-2,4-dicarboxylate (Example 5b)) in 100 ml methanol was added a solution of 4.6 g of 50% aqueous sodium hydroxide in 50 ml methanol. After stirring overnight the salt was isolated by filtration and washed with methanol and vacuum dried yielding 2.5 g (42%) of the title compound as a white hygroscopic solid. An additional 1.8 g (30%) could be isolated by addition of ether to the filtrate of the first sample.
