HCID 131720814-(Piperidin-1-yl)butanoic acid hydrochloride

Procedure

4-Piperidinobutyric acid hydrochloride may be obtained by working according to the method described in Example 4 for the preparation of 1-methyl-3-piperidinecarboxylic acid hydrochloride, but starting with ethyl 4-piperidinobutyrate (19.9 g) and 6N aqueous hydrochloric acid solution (66.5 cc), and by heating for 24 hours under reflux. 4-Piperidinobutyric acid hydrochloride (16.3 g), m.p. 190° C., is thereby obtained.
