Versuchsvorschrift

6 g of NaOH, 23.27 g of 3-chlorosulphonyl-benzothiophene and 13.36 g of sarcosine are added to a mixture of 200 ml of toluene and 200 ml of water and stirred for 6.5 hours at 60° C. For working up, the aqueous phase is separated off and the organic phase is extracted with 100 ml of 2 N NaOH solution. The combined aqueous phases are acidified with conc. HCl and then extracted twice with 300 ml of ethyl acetate. After washing with saturated aqueous saline solution and drying over magnesium sulphate the organic phase is concentrated by evaporation. The crude product obtained is recrystallised from 100 ml of dichloroethane. Yield: 13.14 g. M.p.: 139-140° C.
