Reaction Conditions

Reaction Steps

Dimethylsulfane (8.17 mL, 109.32 mmol, 1.1 eq) was added dropwise to a stirred suspension of N-chlorosuccinimide (14.53 g, 109.32 mmol, 1.1 eq) in dichloromethane (50 mL) at 0° C. The reaction mixture was cooled to −20° C. and (1H-indol-6-yl)(morpholino)methanone (16.0 g, 99.37 mmol, 1.0 eq) in dichloromethane (120 mL) was added dropwise. After stirring for 1 h at room temperature, the solvent was evaporated and replaced by xylene (100 mL). The mixture was refluxed for 1 h, cooled to ambient temperature and then passed through a silica gel column [100-200 mesh, methanol/dichloromethane=1:19]. The product (16.0 g) obtained was used without further purification.
