Electric Literature of 3144-09-0,Some common heterocyclic compound, 3144-09-0, name is Methylsulfonamide, molecular formula is CH5NO2S, 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.
Methane sulfonamide (10 gm) and n-butylacetate (80 mL) were charged into a 250 mL round bottom flask at 30C. Chloroacetylchloride (21 .37 gm) was added slowly over a period of 10 minutes at 30C. Temperature of the reaction mass was raised to 125C and maintained reflux for 16 hours. Progress of the reaction was monitored by TLC and after completion of the reaction the mass was cooled to 20C and stirred for 1 hour at 20C. Reaction mass was filtered and the wet solid was washed with n- butylacetate (10 mL). The wet solid was taken into another 100 mL round bottom flask and n-butylacetate (50 mL) was added and stirred for 30 minutes at 20C. The precipitation was filtered and the solid was suck dried. The material was dried at 45 under vacuum for 5 hours to yield 14 gm of title compound.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route Methylsulfonamide, its application will become more common.
