To prepare 2 - (4 - morpholinyl thio) benzothiazole, the method is as follows:
First take an appropriate amount of 2 - chlorobenzothiazole and place it in the reactor. This is the starting material for the reaction. Compound with an organic solvent such as N, N - dimethylformamide (DMF) or acetonitrile to dissolve it in a homogeneous system so that the subsequent reaction can proceed smoothly.
Prepare another 4 - mercapto-morpholine and slowly add it to the above solution containing 2 - chlorobenzothiazole. When the two meet, there is a possibility of a substitution reaction. In order to promote the reaction, it is often necessary to add alkali substances such as potassium carbonate or sodium carbonate. The effect of alkali, one can combine with the acid generated in the reaction to shift the equilibrium to the right; the other can assist 4-mercapto-morpholine to form sulfur anions, enhance its nucleophilicity, and then more easily with the chlorine atom of 2-chlorobenzothiazole nucleophilic substitution.
When reacting, temperature control is quite critical. Usually in a certain temperature range, such as 50-80 ° C, continuous stirring is required. The purpose of stirring is to fully contact the reactants, speed up the reaction rate, and ensure that the reaction proceeds uniformly. After several hours, the reaction gradually becomes complete.
After the reaction is completed, pour the reaction solution into an appropriate amount of ice water, and the product may precipitate from the solution due to solubility. Then the crude product is obtained by filtration. The crude product still contains impurities and must be purified by recrystallization. A suitable solvent can be used, such as ethanol-water mixed solvent, heating to dissolve the crude product, filtering hot to remove insoluble impurities, until the filtrate cools, the pure product 2- (4-morpholinyl thio) benzothiazole will slowly crystallize, and finally dry to obtain a pure product.
