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
(S)-3-Bromo-7-chloro-5-(phenyl(tetrahydro-2H-pyran-4-yl)methyl)-5H- pyrrolo[2,3-b:4,5-b’]dipyridine (150 mg, 0.328 mmol), thiomorpholine 1,1-dioxide (311 mg, 2.30 mmol) and the triethylamine (0.365 mL, 2.63 mmol) were dissolved in 1.2 mL of DMSO and microwaved at 175 ¡ãC for 2 h. It was diluted with 1percent MeOH/EtOAc and washed twice with brine. The organic layer was dried over MgS04 and concentrated to obtain 181 mg of crude. The crude material was purified via preparative LC/MS with the following conditions: Column: XBridge CI 8, 19 x 200 mm, 5-muiotatauiota particles; Mobile Phase A: 5:95 ACN: water with 10-mM NH4OAc; Mobile Phase B: 95:5 ACN: water with 10- mM NH4OAc; Gradient: 40-80percent B over 15 min, then a 5-min hold at 100percent B; Flow: 20 mL/min. Fractions containing the title compound were combined and dried via centrifugal evaporation. The yield of the product was 76percent. NMR (500MHz, DMSO- d6) delta 8.62 (br. s., 1H), 8.43 (s, 1H), 8.30 (d, J=8.4 Hz, 1H), 7.73 (d, J=7.3 Hz, 2H), 7.32 (t, J=7.5 Hz, 2H), 7.24 (t, J=7.3 Hz, 1H), 7.03 (d, J=8.8 Hz, 1H), 5.61 (br. s., 1H), 4.28 (br. s., 4H), 3.90 – 3.82 (m, 1H), 3.76 (d, J=10.3 Hz, 1H), 3.53 (br. s., 1H), 3.30 – 3.16 (m, 6H), 1.50 – 1.38 (m, 2H), 1.24 (d, J=7.3 Hz, 1H), 1.13 (d, J=l 1.0 Hz, 1H); LC/MS (M+H) = 555.0 [Column: Waters Aquity BEH C18 2.1 X 50 mm 1.7u; Mobile Phase A: water with 0.05percent TFA; Mobile Phase B: ACN with 0.05percent TFA; Temperature: 40 ¡ãC; Gradient: 2-98percent B over 1.5 min; Flow: 0.8 mL/min].
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.
