Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 59801-62-6, name is Thiomorpholine 1,1-dioxide hydrochloride. A new synthetic method of this compound is introduced below. 59801-62-6
To a solution of 7-(3-chloro-phenylamino )-3-methyl-lH-pyrrolo[2,3-c ]pyridine-4-carboxylic acid (150mg) in dimethylformamide (4ml) was added 4-ethylmorpholine (253mul), thiomorpholine 1,1- dioxide hydrochloride (90. mg), 1-hydroxybenzotriazole hydrate (105mg) and 1-(3- dimethylaminopropyl) -3-ethylcarbodiimide hydrochloride (115mg) and the solution stirred at room temperature overnight. The dimethylformamide was evaporated and the residue dissolved in ethyl acetate (40ml) and washed with 5% sodium hydrogen carbonate solution (25ml) and water (25ml). The organic layer was dried (MgS04) and evaporated to give an orange oil. The residue was triturated with diethyl ether to give a white solid which was then filtered off, sucked dry then dried at 40C under vacuum to afford the title compound (75mg). NMR (d6-DMSO) 8 2.11 (3H, s), 2.49-2.57 (8H, m), 6.94 (1H, d), 7.31 (1H, t), 7.38 (1H, s), 7.73 (1H, d), 7.82 (1H, s), 8.32 (1H, s), 9.45 (1H, s), 11.65 (1H, brs). LC/MS [MH+] 419 consistent with molecular formula C19H1935ClN4O3S
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant. 59801-62-6, we look forward to future research findings about .
