Reaction Steps

A solution of 400 mg (1.44 mM) of 4-chloro-6,7-diethoxy-quinoline-3-carbonitrile, 227 mg (1.54 mM) of 6-Amino-1-Indanone and 161 mg (1.44 mM) of pyridine hydrochloride in 12 ml of 2-methoxyethanol was refluxed for 3 hours. To the warm solution was added 1 ml of 1M sodium carbonate and the sample was heated for 5 minutes at 100° C., then poured into 300 ml of ice water. The solid was collected, washed with water followed by ether and dried under vacuum at 80° C. to yield 483 mg of 6,7-Diethoxy-4-(1-oxo-indan-5-ylamino)-quinoline-3-carbonitrile as a white solid: mass spectrum (electrospray, m/e): M+H 388.0, mp=Decomposed at 263° C.
