In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 60-56-0 as follows. Recommanded Product: 1-Methyl-1H-imidazole-2(3H)-thione
General procedure: To a solution containing a thione (1, 6, 8, or 10, 1.0 equiv) in water (2.5 mL) and acetonitrile(1.5 mL) was added saturated aqueous ammonium hydroxide. After the solution was stirred atroom temperature for 30 min, a 3-(chloromethyl)coumarin (2, 1.5 equiv) was added and stirring wascontinued at room temperature for 15 min to 2.0 h. Acetonitrile therein was removed under reducedpressure and water was further removed under reduced pressure over P2O5 with a Kuegelrohr GKR-51apparatus (BUCHI, Flawil, Switzerland). The residue was purified by use of column chromatographypacked with silica gel to give the desired products with purity of >98.0%, as determined by HPLC(see Supplementary Materials).
According to the analysis of related databases, 60-56-0, the application of this compound in the production field has become more and more popular.
