Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 3144-09-0, name is Methylsulfonamide, A new synthetic method of this compound is introduced below., Recommanded Product: Methylsulfonamide
To a stirred suspension of methylsulfonamide (6 g, 62 mmol) in DCM at 0 C. was added DMAP (760 mg, 6.2 mmol), triethylamine (10.4 ml, 74.4 mmol) and (Boc)2O (14.2 g, 65.1 mmol). The reaction mixture was warmed up to room temperature and stirred overnight. The solution was concentrated and the residue was diluted with ethyl acetate, washed consecutively with 1N HCl and water, dried with Na2SO4, filtered and evaporated to afford a colorless oil. The oil was refluxed in hexane for 1 hour then cooled to room temperature and filtered to afford the target compound as a white solid (12.1 g, 42.1% yield). 1H NMR (DMSO-d6, 300 MHz) delta ppm 11.22 (s, 1H), 3.18 (s, 3H), 1.42 (s, 9H).
The synthetic route of 3144-09-0 has been constantly updated, and we look forward to future research findings.
