Reaction Steps
The procedure described in Example 1(b) was followed, using 1.0 g of thiourea, 4.0 g of 1-[4-(4-chlorophenyl)butyl]-4-(3-chloropropyl)piperazine dihydrochloride and 50 ml of reagent ethanol. The hydrolysis was effected with 4.0 g of sodium hydroxide in 50 ml of water. Work-up of the free base, as described above followed by purification on a silica gel column (methylene chloride:methanol, 97:3), precipitation as the hydrochloride salt and recrystallization from reagent ethanol, gave 0.6 g (16% of theory) of 3-{4-[4-(4-chlorophenyl)butyl]piperazin-1-yl}propanethiol dihydrochloride as a white crystalline solid, M.p. 254°-259° C.
