실험 절차

Utilizing the procedure described in Example 1(b), 6.0 g of thiourea, was reacted with 25.2 g of 1-(4-chlorobenzyl-4-(3-chloropropyl)piperazine dihydrochloride and 8.7 g of triethylamine in 200 ml of reagent ethanol. The hydrolysis was effected with 5.0 g of sodium hydroxide in 50 ml of water. Work-up as described above gave 16.6 g (75% of theory) of 3-[4-(4-chlorobenzyl)piperazine-1-yl]propanethiol dihydrochloride as an off-white crystalline solid, M.p. 257°-260° C.
