Reaction of indole with the combination 1-cyclohexyl-2-pyrrolidinone and phosphoric trichloride gives the hydrochloride of 3-(1-cyclohexylpyrrolidin-2-ylidene)-3H-indole. Treatment of this with base at room temperature causes hydrolytic ring opening producing 4(cyclohexylamino)-1-(1 H-indol-3-yl)butan-1-one but careful low-temperature basification allows the isolation of 3-(1-cyclohexylpyrrolidin-2-ylidene)-3H-indole itself. The crystal structure of the hydrochloride, as a dihydrate, was determined.
