| Product | 1-Acetylpiperidine-4-carboxylic acid | HCID 117255 | 97% |
Reaction Steps
Isonipecotic acid (10 grams) (77.5 mmoles) and acetic anhydride (23.7 grams) (232.5 mmoles) were dissolved 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: 12.8 grams, 97%, MH+ 172).
