13006-59-2, 3-Methyl-1H-indole-2-carbonitrile is a indole-building-block compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

Step 1 : A mixture of 3-methyl-lH-indole-2-carbonitrile (500 mg, 3.2 mmol), 2- fluorobenzonitrile (388 mg, 3.2 mmol) and CS2CO3 (1.05g, 3.2 mmol) in DMF (10 mL) was heated at 60 C overnight. The mixture was poured into H20 and a precipitate formed. The solid was collected by filtration, washed with H20 and hexane, and dried under vacuum to give l-(2- cyanophenyl)-3-methyl-lH-indole-2-carbonitrile (780 mg, 94.6 %) as an off white solid that was used without purification.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.227960-12-5,Methyl 5-methylindole-3-carboxylate,as a common compound, the synthetic route is as follows.

To a solution of 5-methyl-1H-indole-3-methyl carboxylate, (CAS 227960-12-5) (3 g, 10.58 mmol) in CH3CN (60 mL) was added cesium carbonate (10.3 g, 31.7 mmol) and the suspension was stirred at reflux temperature for 2 hrs. The mixture was then cooled at 50 C. and 4-(chloromethyl)-1,2-dimethylbenzene, (2.7 g, 17.5 mmol) was added slowly. The reaction mixture was stirred at reflux temperature for 1 hr. The reaction was cooled to room temperature and filtered to remove cesium carbonate, concentrated and gave Intermediate 1 (4.8 g).1H NMR (300 MHz, CDCl3) delta: 7.98 (s, 1H), 7.78 (s, 1H), 7.18-7.28 (m, 1H), 7.01-7.13 (m, 2H), 6.84-6.97 (m, 2H), 5.22 (s, 2H), 3.90 (s, 3H), 2.47 (s, 3H), 2.21 (d, 6H).

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.5192-03-0,1H-Indol-5-amine,as a common compound, the synthetic route is as follows.

A solution of 5-amino indole (2 g, 15.2 mmol) and di-tert-butyl dicarbonate (3.49 g. 15.2 mmol) in dichloromethane (20 ml) was stirred at ambient temperature overnight. The reaction mixture was concentrated under reduced pressure to yield crude (1H-indol-5-yl)-carbamic acid tert-butyl ester (3.47 g) which was used in the next step without further purification.

7506-66-3, cis-Hexahydro-1H-isoindole-1,3(2H)-dione is a indole-building-block compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,7506-66-3

To the foregoing solution, under reflux, was added cis-cyclohexane-1,2-dicarboximide (10.6 g) portionwise over 10 minutes. The reaction mixture was heated to reflux for 3 hours. After cooling to 0 C., water (7 ml) was added followed by 4N sodium hydroxide (7.6 ml) and water (23 ml). The white suspension was stirred whilst warming to room temperature. The solid was removed by filtration then the filtrate dried (sodium sulphate) and evaporated to give a cream oil.
