Some common heterocyclic compound, 37045-73-1, name is 3-(Methylsulfonamido)aniline, molecular formula is C7H10N2O2S, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. Application In Synthesis of 3-(Methylsulfonamido)aniline
Take a 25 mL Schlenk reaction tube, add 74 mg of 3-methanesulfonylaminoaniline, 9 mg of palladium acetate and 80 mg of molecular sieve.93 mg of ethyl 2-oxopropionate, 96 mg of acetic acid and 2 mL of dimethyl sulfoxide were injected, followed by a 200 mL oxygen balloon, and stirred at 70 C for 18 hours.After the reaction was completed, 15 mL of ethyl acetate was added to dilute the reaction mixture, and the filtrate was washed twice with 10 mL of brine, and the organic phase was separated. The aqueous phase was extracted with ethyl acetate. The organic phase was combined and purified by column chromatographyof Ethyl 6-Methanesulfonylamino-1H-indole-2-carboxylate pure product 78mg, yield 69%; ethyl 4-methanesulfonylamino-1H-indole-2-carboxylate pure product 1mg, yield 1 %.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 37045-73-1, its application will become more common.
