Mode opératoire

The procedure described in Example 1(b) was followed, using 7.6 g of thiourea, 22.9 g of 1-[3-(4-chlorophenyl)propyl]-4-(3-chlorophenyl)piperazine dihydrochloride, 5.8 g of triethylamine and 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 14.1 g (65% of theory) of 3-{4-[3-(4-chlorophenyl)propyl]piperazin-1-yl}propanethiol dihydrochloride as a white crystalline solid, M.p. 238°-242° C.
