Versuchsvorschrift
1-Diethylamino ethyl-2-keto-3-phenyl piperazine prepared according to Example 1 B (a) of application Ser. No. 333,497, is reduced by following the procedure described hereinabove in Example 7 (a) whereby, in place of 1-diethylamino ethyl-3-keto-2-phenyl piperazine, the equimolecular amount of said 1-diethylamino ethyl-2-keto-3-phenyl piperazine is reduced. The resulting 3-phenyl piperazine compound is obtained in the form of a light yellow oil boiling at 102° C./0.02 mm. Hg.
