20196-21-8, A common heterocyclic compound, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route., 20196-21-8
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), 20196-21-8
