HCID 867456314-Diisopropylaminobutyric acid hydrochloride

Procedure

4-Diisopropylaminobutyric 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-diisopropylaminobutyrate (9.2 g) and 6 N aqueous hydrochloric acid solution (28.5 cc) and by heating for 6 hours under reflux. 4-Diisopropylaminobutyric acid hydrochloride (8 g), m.p. 136° C., is thereby obtained.
