HCID 8028Tetrahydrofuran溶媒

実験手順

As for Example 27, 3-(3-pyridylcarbonyl)acrylic acid (0.01 mole) is reacted with N,N'-carbonyldiimidazole (0.011 mole) in tetrahydrofuran and to the mixture is added 0.011 mole of L-proline. The mixture is refluxed 16 hours and the solvent removed under reduced pressure. The mixture is partitioned between dichloromethane and water containing acetic acid. The organic layer is separated, washed with water and dried over magnesium sulfate. The solvent is removed in vacuo to yield 1-[3-(3-pyridylcarbonyl)acryloyl]-L-proline. The preceding compound is dissolved in carbon tetrachloride and 0.03 mole of thioacetic acid is added. The mixture is heated 3 hours and the solvent is removed in vacuo to give the product of the Example as a glass.
