実験手順
To 3-(6-bromo-pyridin-3-yl)-acrylic acid methyl ester (120 mg, 0.495 mmol) in THF was added a solution of 0.5 N-LiOH (2 eq) and the mixture was stirred for 3 hrs at room temperature. The resulting residue was dissolved in H2O, then washed three times with Et2O, and neutralized with 1N HCl to pH 5˜7. The resulting solid filtered and washed with H2O and then dried in vacuo to give 3-(6-bromo-pyridin-3-yl)-acrylic acid (100 mg, 88%).
