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.39093-93-1, Thiomorpholine 1,1-dioxide it is a common compound, a new synthetic route is introduced below., 39093-93-1
[3740] A solution of methyl 3-fluoiO-4-((( l-methyl- l H-indazol-4-yl)amino)methyl)benzoate (0.384 g, 1.225 mmol), N,N-diisopropylethylamine ( 1.280 mL, 7.351 mmol) and triphosgene (0.182 g, 0.61 mmol) in dichloromethane (5 mL) was stirred at the room temperature for 30 min, and mixed with thiomorpholine 1 , 1 -dioxide (0.166 g, 1.225 mmol). The reaction mixture was stirred at the same temperature for additional 1 8 hr. Then, water was added to the reaction mixture, followed by extraction with dichloromethane. The bi-phasic mixture was passed through a plastic frit to remove the solid residues and aqueous layer, and the organic layer collected was concentrated in vacuo. The residue was chromatographed (Si02, 12 g cartridge; methanol / dichloromethane = 0 percent to 5 percent ) to give methyl 3-fluoro-4-((N-( l-methyl- l H-indazol-4-yl)- l , l-dioxidothiomorpholine-4-carboxamido )methyl)benzoate as pale yellow oil (0.531 g, 91.3 percent).
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 39093-93-1, and friends who are interested can also refer to it.
