Procedure
In ethanol (45 ml) was dissolved sodium (0.7 g), and diethyl methylmalonate (5.26 ml) and 3-nitrobenzyl chloride (5 g) were added thereto, followed by heating under reflux for 2 hours. The reaction mixture was ice-cooled, an aqueous saturated ammonium chloride was added thereto, followed by extracting with ethyl acetate. The extract was washed with brine, dried over anhydrous magnesium sulfate and the solvent was evaporated, to give the title compound (9.724 g) as a pale yellow oil.
