Reaction Steps

A mixture of 500 mg 5-chloro-1-indanone, 1.33 g oxindole and 0.5 ml piperidine in 3 ml dimethylforamide was heated in a sealed tube at 95° C. overnight. Water was added to the reaction mixture to yield.an oily solid. The mixture was sonicated for a few minutes then decanted. This washing procedure was repeated several times. The solid was then filtered and washed with ethyl acetate/hexanes (1:3) to yield 172 mg of 3-(5-chloroindan-1-ylidene)-1,3-dihydroindol-2-one as a mustard colored solid.
