実験手順

The (3-Methyl-4-nitrophenyl)acetic acid (0.143 g) obtained in Example 1-3b) was dissolved in methylene chloride (5 mL). To the solution were added 2-hydroxymethyl-2-phenylmalonic acid diethyl ester (0.195 g) obtained in Example 1-2a), 4-dimethylaminopyridine (0.090 g) and 1-ethyl-3-(3′-dimethylaminopropyl)carbodiimide hydrochloride (0.141 g), and the mixture was stirred at room temperature overnight. The reaction mixture was concentrated and the residue was purified by column chromatography on silica gel with ethyl acetate:hexane=1:4 to give the title compound (0.219 g) as a yellow oil.
