Procedure
In analogy to example 63, step 4, from [4-(5-chloro-2-methyl-phenyl)-piperazin-1-yl]-[(3S,4S) or (3R,4R)-4-(4-fluoro-2-methyl-phenyl)-piperidin-3-yl]-methanone hydro-chloride and 3-chlorobenzenesulfonyl chloride was prepared [(3S,4S) or (3R,4R)-1-(3-chloro-benzenesulfonyl)-4-(4-fluoro-2-methyl-phenyl)-piperidin-3-yl]-[4-(5-chloro-2-methyl-phenyl)-piperazin-1-yl]-methanone as a white foam, MS: 604.0 ([M+H, 1Cl])+; [α]D=−32.13 (c=0.426 g/100 mL, CHCl3).
