A solution of monochloroacetic acid (9.35 g.) in water (40 ml.) was adjusted to pH 8.0 with a solution of sodium hydroxide (4.0 g.) in water (30 ml.). Piperidine (8.0 ml.) was then added and the mixture was left at room temperature for 2 days and then heated on a steam bath for 2 hr. The solution was then evaporated and the residue was digested with hot ethanol, filtered and the filtrate was evaporated to give piperidinoacetic acid (12.55 g.) as a brown glass.
