Reaction Steps

A mixture of 0.5 g 5-amino-1-indanone, 1.3 g oxindole and 3 ml piperidine in 5 ml of dimethylforamide was heated in a sealed tube at 130° C. for 3 days to yield a reddish-black suspension. The mixture was added to 1N hydrochloric acid and extracted with ethyl acetate. The organic layer was washed with brine, dried with magnesium sulfate and concentrated. Chromatography afforded 45 mg of 3-(5-aminoindan-1-ylidene)-1,3-dihydroindol-2-one as a brown solid.
