Procedure

A mixture of 0.5 g 5-dimethylamino-1-indanone, 1.1 g oxindole and 2.5 ml piperidine in 4 ml dimethylforamide was heated in a sealed tube at 130° C. for 12 hours to yield a reddish-black suspension. The mixture was added to 1N hydrochloric acid solution and extracted with ethyl acetate. The organic layer was washed with brine, dried with magnesium sulfate and concentrated. Chromatography afforded 35 mg of 3-(5-dimethylamino-indan-1-ylidene)-1,3-dihydroindol-2-one as a brown solid.
