YieldReaction ConditionsOperation in experiment
83% In quinoline; for 1h;Reflux;Product distribution / selectivity; <strong>[1075-34-9]5-bromo-2-methylindole</strong> (6.00 g, 28.6 mmol) was dissolved in quinoline (50 mL).Copper cyanide (7.46 g, 83.3 mmol) was added.The mixture was refluxed for 1 hour.The mixture was cooled to room temperature, diluted with EtOAc (500 mL) and washed with ice-cold hydrochloric acid (1M).The organic layer was washed with brine, dried over MgSO4, filtered and evaporated to dryness.Flash chromatography (silica, heptanes:EtOAc 1:1) gave 2-methyl-1H-indole-5-carbonitrile as a brown solid (4.11 g, 83percent).
83% In quinoline; for 1h;Reflux; <strong>[1075-34-9]5-bromo-2-methylindole</strong> (6.00 g, 28.6 mmol) was dissolved in quinoline (50 mL). Copper cyanide (7.46 g, 83.3 mmol) was added. The mixture was refluxed for 1 hour. The mixture was cooled to room temperature, diluted with EtOAc (500 mL) and washed with ice-cold hydrochloric acid (1 N). The organic layer was washed with brine, dried over MgS04, filtered and evaporated to dryness. Flash chromatography (silica, heptanes: EtOAc 1 :1 ) gave 2-methyl-1 H-indole-5-carbonitrile as a brown solid (4.1 1 g, 83percent).
80% In quinoline; for 1h;Reflux; A round bottomed flask was charged with <strong>[1075-34-9]5-bromo-2-methylindole</strong> (20.0 g, 95.2 mmol) in quinoline (200 mL). Copper cyanide (13.30 g, 148.5 mmol) was added. The mixture was refluxed for 1 hour. Formation of a dense precipitate impeded the stirring early in the reaction, later on the precipitate disappeared. The mixture was cooled to room temperature and poured into EtOAc (0.5 L) and 6N HCl (250 mL). The mixture was filtered. The filtrate was thoroughly washed with ice-cold hydrochloric acid (2M). The organic layer was then washed with brine, dried over MgSO4 and evaporated to dryness. Flash chromatography (silica, EtOAc:heptane 1:1) gave 2-methyl-1H-indole-5-carbonitrile (13.0 g, 80percent) as a light-brown powder, Mp 125-7
49% In 1-methyl-pyrrolidin-2-one; at 150℃; for 3h; 2-methyl-lH-indole-5-carbonitrile; [00368] A suspension of 5-bromo-2-methyl-lH-indole (5.07 g, 24.1 mmol) and copper(I) cyanide (10.8 g, 121 mmol) was heated in N-methyl pyrrolidinone (34.5 mL) at 150 °C. After 3 hours, the reaction was quenched by the addition of water (100 mL), and diluted in ethyl acetate (100 mL). Ethylenediamine (30 mL) was added and the biphasic mixture was stirred for 15 minutes. The organic layer was extracted with ethyl acetate (4 x 250 mL), washed with brine (3 x 200 mL), dried (sodium sulfate), filtered, and concentrated to a brown residue. Purification was achieved by column chromatography on silica gel (Luknova 40g, 20 mL/min) using 25-60percent ethyl acetate in hexanes over 60 minutes to afford 2-methyl-lH- indole-5-carbonitrile (1.85 g, 1 1.9 mmol, 49 percent yield) as a white solid. NMR (400 MHz, CDC13) delta (ppm): 8.15 (br. s, 1H), 7.86 (d, 1H), 7.31-7.55 (m, 2H), 6.30 (s, 1H), 2.48 (s, 3H).

YieldReaction ConditionsOperation in experiment
87%Chromat. Under a nitrogen atmosphere, cuprous iodide (3.0 molpercent, 0.7 mg), sodium iodide (1.0 equiv. 18.7 mg) and magnets were charged into a previously baked 10 mL glass pressure tube. Dioxane (0.2 mL), <strong>[1075-34-9]5-bromo-2-methylindole</strong> (0.125 mmol, 1.0 equiv., 26.3 mg) and N,N'-dimethylethylenediamine (10.0 molpercent, 1.1) were then added. Mg). Added, The glass pressure tube was placed in a metal module that had been preheated to 100[deg.] C. and stirred for 10 hours. After cooling to room temperature, copper iodide (20 molpercent, 4.8 mg), ferrous chloride (3 molpercent, 0.5 mg), N-methylpyrrolidone (0.5 mL) and diethoxymethylsilane were added under a nitrogen atmosphere. (3.0 equiv., 50.4 mg). The tube was purged of air and charged with carbon dioxide (5.0 equiv., 15 mL) and ammonia gas (5.0 equiv., 15 mL). After the addition was completed, the reactor was placed in a metal module preheated to 160C and stirred for 10 hours. After the reaction was completed, the reaction system was cooled to room temperature and pressure was slowly released. Using dodecane as an internal standard, the yield of the gas chromatography was 87percent.
