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. 3144-09-0, name is Methylsulfonamide belongs to amides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. 3144-09-0
Reference Example 42 To a mixture of methane sulfonamide (1.96 g), triethylamine (3.2 mL), 4-(dimethylamino)pyridine (252 mg), and dichloromethane (30 mL) was added a mixture of di-tert-butyl dicarbonate (5.17 g) and dichloromethane (40 mL) at room temperature for 30 minutes. The mixture was concentrated after stirring for 2 hours, and the residue was distributed with ethyl acetate and 1 N hydrochloric acid. The organic layer was washed with water, dried and concentrated. The obtained residue was purified by silica gel column chromatography to obtain tert-butyl methylsulfonyl carbamate (2.44 g). 1H-NMR (300 MHz, CDCl3) delta: 1.52 (9H, s), 3.28 (3H, s).
The synthetic route of 3144-09-0 has been constantly updated, and we look forward to future research findings.
