実験手順
By using a method similar to that described in Example 35, but starting from 3-dimethylaminoacrylophenone (5 g), phosphorus oxychloride (2.5 cc), p-chlorothiophenol (4.13 g) and sodium cyanoborohydride (1 g), and after evaporating the reaction mixture under reduced pressure (2.7 kPa) at 40° C., a residue is obtained, which is dissolved in ethanol (50 cc). A 3N solution (12 cc) of hydrochloric acid gas in ethyl ether is added to this solution. The precipitate formed is separated off by filtration and then recrystallised from ethanol (70 cc). In this way 3-(4-chlorophenylthio)-1-dimethylamino-3-phenylthio-2-propene (Z) hydrochloride (3.4 g) is obtained in the form of a white powder melting at 226° C.
