Reaction Steps

11.9 gram of 1-[2-(2,4-Dimethylphenylsulfanyl)-phenyl]piperazine oil was dissolved in 100 ml ethanol using heating. When a homogenous solution was obtained addition of 3.5 ml conc. HCl (aq) took place causing the immediately precipitation of a white solid. The suspension was stirred for 5 minutes at first and then on ice-bath another hour before filtration. The white solid was washed using 100 ml of fresh cool ethanol (placed in freezer at −18° C. for 2 hours), 50 ml acetone and finally 50 ml diethyl ether before dried in vacuum (50° C.) overnight. 1-[2-(2,4-Dimethylphenylsulfanyl)-phenyl]piperazine HCl was isolated in 5.1 gram (38%). NMR complies with structure. Elemental analysis: 61.23%; C, 7.91%; N, 7.16%; H (Theory for 1:1 salt monohydrate: 61.26%; C, 7.94%; N, 7.14%; H)
