実験手順

50 mg of 3-[1-(2,4-dimethoxybenzyl)-2-oxo-1,2,5,6-tetrahydro-pyridin-3-yl]-propionic acid (0.157 mM) was dissolved in 1 ml of trifluoroacetic acid solution. Then 0.074 ml of triethyl silane (0.465 mmol) was added thereto and the mixture was heated for 20 min at 80° C. The solvent was removed in vacuo and the remaining residue was recrystallized with mixture solution of methanol and ethylacetate to give 13 mg of 3-(2-oxo-1,2,5,6-tetrahydro-pyridin-3-yl)-propionic acid (g) (yield: 50%).
