3676-85-5, name is 5-Aminoisoindoline-1,3-dione, belongs to indolines-derivatives compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. category: indolines-derivatives
A solution of 400 mg (1.44 mM) of 4-chloro-6,7-diethoxy-quinoline-3-carbonitrile and 305 mg (1.88 mM) of 4-Aminophthalimide in 10 ml of ethanol 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 100C, then poured into 300 ml of ice water. The solid was collected, washed with water followed by ether and dried under vacuum at 80C to yield 348 mg of 4-(1,3-Dioxo-2,3-dihydro-1H-isoindol-5-ylamino)-6,7-diethoxy-quinoline-3-carbonitrile as a yellow solid: mass spectrum (electrospray, m/e): M+H 402.9, mp = 248-251C.
The synthetic route of 3676-85-5 has been constantly updated, and we look forward to future research findings.
