Acetic Anhydridewith Alcohols in thePresence of Pyridine. A group of of pyridine acetyl chloride is a more reactive acetylating agent than acetic anhydride.
On addition of alcohol the amino acid crystallized. It With phenylmethylaminoacetic acid no loss of carbon dioxide occurs; simple acetylation takes place.

pyridine acetic anhydride and an alcohol. This observation was tested by varying the concentra tion of perchloric acid in an acetic anhydride-pyridine rea.
Although several reagents1 are available for the acetylation of alcohols an acetic anhydride–pyridine mixture is most commonly used for this purpose. 4
