Tag: 20196-21-8

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.20196-21-8,Thiomorpholin-3-one,as a common compound, the synthetic route is as follows.

Example 10 2-[2-(4-Methylpiperazin-1-yl)-benzylidene]-thiomorpholin-3-one Sodium hydride (930 mg, 23.3 mmol of 60% oil dispersion) was washed with hexanes under a nitrogen atmosphere and suspended in 100 mL of anhydrous THF. Thiomorpholin-3-one (1.0 g, 8.55 mmol) was added, followed immediately by 2-(4-methylpiperazin-1-yl)-benzaldehyde (1.58 g., 7.75 mmol). The reaction was then heated to reflux overnight, cooled to room temperature and concentrated in vacuo. The residue was dissolved in methylene chloride and washed with aqueous ammonium chloride (NH4CI) and saturated brine and then dried with MgSO4. Purification using flash chromatography gave 2-{hydroxy-[2-(4-methylpiperazin-1yl)phenyl]-methyl}-thiomorpholin-3-one as a white solid, m.p. 137-139 C.

20196-21-8 Thiomorpholin-3-one 88402, aThiomorpholine compound, is more and more widely used in various.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.20196-21-8,Thiomorpholin-3-one,as a common compound, the synthetic route is as follows.

Step B Thiomorpholin-3-thione A mixture of 1.17 g (10 mmol) of thiomorpholin-3-one and 11 mmoles of Lawesson’s reagent in 25 mL of toluene was heated to reflux 2 hrs. The reaction mixture was cooled and the solvent was removed to give a residue. This was taken up in methylene chloride and applied on silica gel column and eluted with ethyl acetate containing methylene chloride (10%). The desired thiomorpholin-3-thione in 65% yield as a solid. 1 H NMR (CDCl3): 2.90(m,2H); 3.62(m,2H); 3.76(s,2H); 8.65(b,1H)

As the paragraph descriping shows that 20196-21-8 is playing an increasingly important role.
