| Abstract: | 2-(1-Iodoethyl)-3,5-dimethyl-1-(4-methylphenylsulfonyl)-2,3-dihydro-1H-indole reacted with pyridine, piperidine, N-alkylpiperidines, and dimethylformamide to give dehydrohalogenation and halogen substitution products whose ratio depended on the reagent structure. Heating of 2-(1-iodoethyl)-3,5-dimethyl-1-methylsulfonyl-2,3-dihydro-1H-indole with piperidine resulted in the formation of only dehydroiodination products. |
