Procedure
For the preparation of the compound of Example 27, 4-(2-methoxyethoxy)benzophenone is obtained by reaction of 4-hydroxybenzophenone with 2-methoxyethyl chloride at 100° C. in the presence of sodium hydride in dimethylformamide. Further reaction takes place in accordance with Example 1-5. 4-(2-Methoxyethoxy)benzophenone is reduced to 4-(2-methoxyethoxy)benzhydrol using sodium borohydride. 4-(2-Methoxyethoxy)benzhydrol is reacted with thionyl chloride in chloroform to give 4-(2-methoxyethoxy)benzhydryl chloride. 4-(2-methoxyethoxy)benzhydryl chloride is reacted with piperazine in dimethylformamide in the presence of potassium carbonate to give 1-((4-(2-methoxyethoxy)phenyl)phenylmethyl)piperazine.
