실험 절차

4-Piperidinylacetic acid (5 grams) (35.0 mmoles) was reacted with acetic anhydride (10.7 grams) (105.0 mmoles) in MeOH (100 ml.) and the mixture was stirred at 25° C. for 24 hours. The mixture was evaporated to dryness and the residue was azeotroped with toluene to give the title compound (Yield: 6.4 grams, 99%, MH+ 185).
