Synthetic Route of 6872-06-6, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 6872-06-6, name is 2-Methylindoline belongs to indolines-derivatives compound, it is a common compound, a new synthetic route is introduced below.
26.6 mg (0.2 mmol) of 2-methylindoline,81.2 mg of ethyl bromodifluoroacetate (0.4 mmol),2.5 mg (0.02 mmol) of cuprous acetate, 19.1 mg (0.04 mmol) of X-phos, 32.7 mg (0.2 mmol) of cesium carbonate were added to 2 mL of DMF solvent.The reaction was carried out at 110 C for 12 hours, after the reaction was completed, it was cooled, filtered, and the filtrate was evaporated.The solvent was removed and the residue was chromatographed on silica gel.It was washed with a mixed solution of petroleum ether and ethyl acetate in a volume ratio of 8:1.The effluent was collected according to the actual gradient, detected by TLC, and the effluent containing the product was combined.The solvent was distilled off by a rotary evaporator. Vacuum drying to give a yellow liquid 2-methylindoline-1-carbaldehyde19.7 mg, yield 61%.
The synthetic route of 2-Methylindoline has been constantly updated, and we look forward to future research findings.
