Versuchsvorschrift

To 5-(2-oxopyrrolidin-1-yl)-biphenyl-3-carboxylic acid methyl ester (D10) (23 mg, 0.078 mmol) in dioxane (2 ml) was added LiOH (5 mg, 0.117 mmol) and water (1 ml) and stirred at room temperature for 2 hours. The solvent was then evaporated to dryness and the residue was partitioned between ethyl acetate and water. The aqueous layer was separated and acidified to pH=1. The product precipitated in the aqueous layer and was removed by filtration and dried in vacuo to afford D11 (10 mg) as white solid.
