Reaktionsschritte
The procedure described in Example 1(b) was followed, using 12.7 g of thiourea and 26.0 g of 1-(4-chlorobenzyl)-2,5-dimethyl-4-(3-chloropropyl)piperazine in 250 ml of reagent ethanol. The hydrolysis was effected with 10.0 g of sodium hydroxide in 50 ml of water. Work-up, as described above, gave 26.5 g (83% of theory) of 3-[4-(4-chlorobenzyl)-2,5-dimethylpiperazin-1-yl]propanethiol dihydrochloride as a white crystalline solid, M.p. 168°-171° C.
