The synthesis method of 2-bromo-1,3-benzothiazole has been recorded in many books in the past, but now it is said by Jun Chen.
First, o-aminothiophenol and bromoacetyl bromide are prepared by condensation reaction. O-aminothiophenol and bromoacetyl bromide interact with each other in a suitable solvent, such as dichloromethane, catalyzed by a base, such as triethylamine. After nucleophilic substitution and cyclization, 2-bromo-1,3-benzothiazole can be obtained. This reaction condition is mild and the yield is quite high. However, the raw material bromoacetyl bromide is corrosive, and the operation needs to be cautious. < Br >
Second, 2-aminobenzothiazole is used as the starting material and obtained by bromination reaction. The reaction of 2-aminobenzothiazole with brominating reagents, such as N-bromosuccinimide (NBS), is initiated by light or heat in an inert solvent, such as carbon tetrachloride, in the presence of an initiator, such as benzoyl peroxide. In this process, a bromine atom replaces the ortho-hydrogen atom of the amino group to form the target product. The method is simple to operate and the raw materials are easy to obtain, but the selectivity of the reaction needs to be carefully regulated to prevent the formation of polybrominated by-products.
Third, it is synthesized by multi-step reaction with o-haloaniline and thiocyanate as raw materials. 2-Bromo-1,3-benzothiazole can be obtained by the reaction of o-halogenated aniline with thiocyanate, and then by cyclization, bromination and other steps. This route is slightly complicated, but the raw materials are widely sourced and the cost is low, which has its advantages in large-scale preparation.
There are many methods for synthesizing 2-bromo-1,3-benzothiazole, each with its own advantages and disadvantages. Experimenters should choose the appropriate method according to their own needs, such as raw material availability, cost considerations, product purity requirements, etc., and operate carefully to obtain satisfactory results.

2-Bromo-1,3-benzothiazole is an organic compound. When using it, many key matters need to be paid attention to.
First safety protection. This compound may be toxic, irritating, and comes into contact with vulnerable skin, eyes and respiratory tract. Be sure to wear protective clothing, protective gloves and goggles, and operate in a well-ventilated manner. If conditions permit, preferably in a fume hood to prevent the inhalation of harmful gases.
Furthermore, pay attention to its chemical properties. 2-Bromo-1,3-benzothiazole contains bromine atoms, which are highly active and can participate in a variety of chemical reactions. Study its chemical properties and reaction mechanism in detail before use, and precisely control the dosage and reaction conditions according to the reaction requirements. For example, when it comes to nucleophilic substitution reactions, it is necessary to consider the effects of reaction substrate activity, solvent type and temperature on the reaction, and select appropriate reaction conditions to promote the smooth progress of the reaction and improve the purity and yield of the product.
Storage should not be ignored. It should be stored in a cool, dry and well-ventilated place, away from fire and heat sources, and away from direct sunlight. Store separately from oxidants, acids, bases, etc., and avoid mixed storage to prevent dangerous reactions. Because of its certain chemical activity, improper storage or deterioration will affect the use effect.
The operation process should be strictly standardized. Accurate measurement should be used to avoid waste and pollution. After the reaction is completed, properly dispose of the remaining reagents and products, follow relevant environmental protection regulations, and do not dump at will to prevent environmental pollution. Wash the experimental equipment in time after use to avoid residual compounds affecting the follow-up experiments.
