Reaction Steps

A MeOH solution (100 mL) containing methyl 3,4-dimethoxyphenylcyanoacetate (1.2 g, 5.1 mmol), TFA (1 mL), and 50 mg of 10% Pd/C was shaken on a Parr shaker for 20 hours under 30 psi of hydrogen. The reaction was filtered, concentrated, dissolved in H2O, and extracted 2× with Et2O. The pH was adjusted to ~10 and the mixture extracted 3× with EtOAc. The EtOAc fractions were dried over Na2SO4 and concentrated to yield 400 mg (32%) of the title compound.
