EXAMPLE 111 6,7-Diethoxy-4-(3-oxo-1,3-dihydro-isobenzofuran-5-ylamino)-quinoline-3-carbonitrile A solution of 400 mg (1.44 mM) of 4-chloro-6,7-diethoxy-quinoline-3-carbonitrile, 230 mg (1.54 mM) of 6-Aminophthalide and 161 mg 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 535 mg of 6,7-Diethoxy-4-(3-oxo-1,3-dihydro-isobenzofuran-5-ylamino)-quinoline-3-carbonitrile as a white solid: mass spectrum (electrospray, m/e): M+H 390.1, mp=280-284 C.
As the paragraph descriping shows that 57319-65-0 is playing an increasingly important role.
