実験手順

4-Chlorophenylhydrazine hydrochloride (1 g) and 4-[(2,2-diethoxyethyl)thio]-1-(phenylmethyl)piperidine (prepared in Example 12) in isopropanol (20 ml) are stirred at room temperature under nitrogen until a solution is formed. After cooling to 0° C., the solution is saturated with gaseous hydrogen chloride. After 4 hours, the precipitate is filtered off, taken up in sodium hydroxide and extracted with ether and then with ethyl acetate. The combined organic phases are dried over sodium sulfate and concentrated. The residual oil is taken up in a solution of hydrogen chloride in ether to give 5-chloro-3-[[1-(phenylmethyl)piperidin-4-yl]thio]-1H-indole hydrochloride (1.4 g).
