Reaction Steps

A mixture of (E)-3-(5-formyl-pyridin-2-yl)-acrylic acid tert-butyl ester (described in Example 11 STEP A-D, 250 mg, 1.07 mmol) and TFA (1 ml) in DCM (4 ml) was stirred at room temperature for 6 h. The solvent was then removed in vacuo and the solid was triturated with Et2O to give 272 mg of (E)-3-(5-formyl-pyridin-2-yl)-acrylic acid as its trifluoroacetate salt.
