Introduction of a new synthetic route about 5-Bromo-2-(chloromethyl)pyridine hydrochloride

At the same time, in my other blogs, there are other synthetic methods of this type of compound,936342-91-5, 5-Bromo-2-(chloromethyl)pyridine hydrochloride, and friends who are interested can also refer to it.

With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.936342-91-5, name is 5-Bromo-2-(chloromethyl)pyridine hydrochloride, molecular formula is C6H6BrCl2N, molecular weight is 242.9285, as common compound, the synthetic route is as follows.Formula: C6H6BrCl2N

5-bromo-2-chloromethyl-pyridine (486mg, 2mmol) and thiomorpholine 1,1-dioxide (406mg, 3mmol) was dissolved in N, N- dimethylformamide (10ml) and then potassium carbonate (986mg, 7mmol), the reaction was stirred for 12 hours at room temperature, 100ml of water was added to the reaction mixture was cooled, (100ml * 3) and extracted with ethyl acetate, then with saturated sodium chloride solution (100ml * 2), dried the organic phase was dried over anhydrous magnesium sulfate filtered, and concentrated under reduced pressure to give 1- (5-bromo – pyridin-2-ylmethyl) – (1,1-dioxo – thiomorpholine) – piperazine (499 mg of the , white solid), yield: 81.8percent.
