N-Methylaniline reacted with ethylene glycol in the presence of a homogenous ruthenium catalyst (1 molpercent based on ethylene glycol) to give 1-methylindole in 51percent yield.Similarly, aniline reacted with 2,3-butanediol affording 2,3-dimethylindole in 58percent yield.The yields of indoles were affected by the molar ratio of aminoarene to glycol.
