With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.5457-28-3,1H-Indole-3-carbonitrile,as a common compound, the synthetic route is as follows.,5457-28-3
To a solution of 3-cyanoindole (1.0 g, 7.03 mmol) in DMC (10 ML), DABCO (0.079 g, 0.70 mmol) is added and the resulting solution is heated to reflux for 8 h.The reaction is cooled to RT, and diluted with EtOAc (40 ML) and H2O (40 ML).The organic layer is separated and washed in sequence with H2O (50 ML), 10% aqueous citric acid (2*40 ML) and H2O (4*40 ML).The organic layer is dried over anhydrous Na2SO4, filtered and concentrated under vacuum to give 3-cyano-1-methylindole (about 1.08 g, 98%) as an oil: 1H NMR (CDCl3) delta 7.74 (d, 1H), 7.53 (s, 1H), 7.40-7.28 (m, 3H), 3.83 (s, 3H); 13C NMR (CDCl3) 136.0, 135.6, 127.8, 123.8, 122.1, 119.8, 116.0, 110.4, 85.4, 33.6; MS m/z 156 [M+1]+.
5457-28-3 1H-Indole-3-carbonitrile 230282, aindole-building-block compound, is more and more widely used in various.
