Reaction Steps

The commercially available 2-tert-butyl-malonic acid diethyl ester (1 g, 4.6 mmol) is dissolved in EtOH (7 mL). A 1N NaOH solution (5.06 mL, 5.06 mmol) is added and the resulting mixture is stirred at 40° C. overnight. Next, the mixture is acidified to pH=1 with HCl. Extraction with EtOAc gives an organic phase that is dried over MgSO4, filtered and evaporated to give the desired product.
