Versuchsvorschrift
To 1-(4-fluorophenyl)-5-oxopyrrolidine-3-carboxylic acid 51 was added 80 mL of CH2Cl2, 30 mL of MeOH, and 1.0 mL of concentrated H2SO4. After heating at reflux overnight, the mixture concentrated and triturated with water to give methyl 1-(4-fluorophenyl)-5-oxopyrrolidine-3-carboxylate 52.
