実験手順
The 2-[2-(3-Methyl-4-nitrophenyl)acetoxymethyl]-2-phenyl-malonic acid diethyl ester (0.219 g) obtained in Example 1-3c) was dissolved in methanol (3 mL). The solution was subjected to hydrogenation in the presence of 7.5% palladium-carbon (0.030 g) under normal pressure to give the title compound (0.197 g) as a yellow oil.
