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.76176-87-9, Thiomorpholine-1-oxide hydrochloride it is a common compound, a new synthetic route is introduced below., 76176-87-9
Example 1.048-[l-(3,5-difluorophenyl)pyrrolidin-2-yl]-2-morpholino-6-[(l-oxidothiomorpholin-4- yl)carbonyl] -4H-chromen-4-oTBTU (176 mg, 0.55 mmol) was added in one portion to a stirred solution of 8-(l-(3,5- difluorophenyl)pyrrolidin-2-yl)-2-morpholino-4-oxo-4H-chromene-6-carboxylic acid (125 mg, 0.27 mmol) and DIPEA (0.286 mL, 1.64 mmol) at room temperature and stirred for 2.5 h. Thiomorpholine 1 -oxide hydrochloride (85 mg, 0.55 mmol) was added to the reaction mixture and stirring was continued for 3 h. The reaction mixture was diluted with DCM, washed with water, brine, dried over MgSC^ and concentrated. The residue was purified by preparative HPLC. The fractions were evaporated to dryness, the residue was dissolved in DCM, dried over MgSC^ and concentrated. The remaining solid was triturated with diethyl ether, filtered, washed with diethyl ether and dried under vacuum at 50C to afford 8-[l-(3,5-difluorophenyl)pyrrolidin-2-yl]-2-morpholino-6-(l-oxo-l,4- thiazinane-4-carbonyl)chromen-4-one (87 mg, 57%) as a pale beige solid.Mass Spectrum: m/z [M+H]+ = 558.Proton NMR Spectrum : (DMSO-d6) 1.75-1.86 (m, 1H), 1.98-2.08 (m, 2H), 2.14 (bs, 0.5H), 2.51-2.58 (m partially hidden by DMSO-d5, 1H), 2.64 (bs, 1H), 2.81 (bs, 1.5H), 2.98 (bs, 1H), 3.27 (bs, 1H), 3.40 (bs, 1H), 3.49-3.65 (m, 5H), 3.64-3.83 (m, 6H), 4.21 (bs, 0.5H), 4.34 (bs, 0.5H), 5.25 (d, 1H), 5.62 (s, 1H), 6.13 (d, 2H), 6.34 (t, 1H), 7.18 (s, 1H), 7.87 (d, 1H)
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. 76176-87-9. We look forward to the emergence of more reaction modes in the future.
