|  |  | 5-Methoxyindole Usage And Synthesis | 
 | Chemical Properties | white to light brownish crystalline powder |  | Uses | 5-Methoxyindole (cas# 1006-94-6) is a compound useful in organic synthesis. It can be used to synthesis 1-(Phenylsulfonyl)-5-methoxy-1H-indole. |  | Preparation | The synthesis of 5-methoxyindole from 5-methoxy-2-oxindole: Conversion of 5-methoxy-2-oxindole to 5-methoxyindole was accomplishedby the chlorination of 5-methoxy-2-oxindole with triphenylphosphine-carbontetrachloride in acetonitrile followed by the catalytic reduction of a chlorine atom in 66% total yield. |  | Definition | ChEBI: 5-methoxyindole is a member of indoles. |  | Reactions | 5-methoxyindole was treated with sodium hydroxide and phenylsulfonyl chloride in the presence of a catalytic amount of tetrabutylammonium bromide to afford 1-(phenylsulfonyl)indole and 5-methoxy-1-(phenylsufonyl)indole in excellent yields of 100%. |  | Synthesis Reference(s) | Journal of Heterocyclic Chemistry, 26, p. 1405, 1989 DOI: 10.1002/jhet.5570260533 The Journal of Organic Chemistry, 58, p. 5558, 1993 DOI: 10.1021/jo00072a052
