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.
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
A mixture isopropyl 4-((lr,4r)-4-(5-chloropyrazin-2-yloxy)cyclohexyloxy)piperidine-l- carboxylate (50 mg, 0.126 mmol), diacetoxypalladium (2.8 mg, 0.013 mmol), thiomorpholine- 1 ,1-dioxide (17 mg, 0.126 mmol), sodium 2-methylpropan-2-olate (29 mg, 0.302 mmol), and l ,l’-3/4w(di-t-butylphosphino)ferrocene (12 mg, 0.025 mmol) in 1 ,4-dioxane (0.8 mL) was heated at 100 ¡ãC for 1 h under microwave irradiation. LCMS showed product had formed and no starting material remained. Water was added to the reaction mixture and it was extracted with DCM (3 x 15 mL). The organic layer was rinsed with brine, dried with Na2S04 and concentrated to give a brown oil. The brown oil was purified using Biotage.(TM). flash chromatography and a 25 g SNAP.(TM). column, 20-100percent EtOAc-hexanes, 15 column volumes. Fractions containing product were combined and concentrated to give the title compound (25 mg, 0.050 mmol, 40.1 percent yield) as a light brown solid. ‘H NMR (CDCI3 , 400 MHz) delta 1.23 (d, J = 4 Hz, 6H), 1.46-1.55 (m, 6H), 1.77-1.82 (m, 2H), 1.96-2.01 (m, 2H), 2.09-2.14 (m, 2H), 3.06 (t, J = 4Hz , 4H), 3.09-3.16 (m, 2H), 3.48-3.52 (m, 1H), 3.54-3.59 (m, 1H), 3.78-3.84 (m, 2H), 4.06 (t, J = 4Hz , 4H), 4.85-4.94 (m, 2H), 7.73 (s, 1H), 7.82 (s, 1H), LCMS m/z: 497.6 [M+H]+.
