Reaction Steps

1-Benzyloxy benzyl-2-phenyl-3-keto piperazine prepared according to Example 12, is reduced by following the procedure described hereinabove in Example 8a whereby, in place of 1-diethylamino ethyl-3-keto-2-phenyl piperazine, the equimolecular amount of said 1-benzyloxy benzyl-2-phenyl-3-keto piperazine is used.
