Reaction Conditions

Reaction Steps

To a mixture of cis-3-aminomethylcyclopentancarboxylic acid (0.2 g, 1.4 mmol) in pyridine (about 5 mL) was added acetic anhydride (about 1 mL) and the mixture stirred at about 70° C. for about 2 h. The solvent was removed under reduced pressure, water was added several times and evaporated in vacuo. A light, viscous oil was obtained and dried in vacuo over acetone reflux to give 0.25 g (97%) of cis-3-[(methylcarbonylamino)methyl]cyclopentancarboxylic acid.
