To prepare 2 - (4 - methylphenyl) - 1, 3 - benzothiazole, there are many methods, and each has its advantages and disadvantages, so it needs to be selected according to the facts.
First, 4 - methylthiophenol and anthranilic acid can be prepared by condensation and cyclization. First, 4 - methylthiophenol and anthranilic acid are mixed in a suitable solvent in proportion, such as toluene or xylene, and an appropriate amount of catalyst, such as concentrated sulfuric acid or p-toluenesulfonic acid, is added. During the reaction, the sulfur atom in 4 - methylthiophenol is condensed with the carboxyl group of anthranilic acid, and the amino group reacts with another part to form a ring to obtain the target product. This process requires temperature control at 150-200 ° C, and the reaction time is about 6-10 hours. The raw materials of this method are easy to prepare, and the operation is not complicated. However, the reaction conditions are harsh and the yield may be limited.
Second, 4-methylbenzaldehyde and 2-aminothiophenol are used as materials and condensed in acidic medium. Dissolve the two in a specific ratio into ethanol or ethyl acetate, and add a little hydrochloric acid or sulfuric acid to catalyze. 4-Methylbenzaldehyde carbonyl is condensed with 2-aminothiophenol amino, and then 2- (4-methylphenyl) -1,3-benzothiazole is obtained by intramolecular cyclization. The reaction temperature should be controlled at 60-80 ℃ for 4-8 hours. The reaction conditions of this method are mild and the yield is high, but the stability of the raw material 4-methylbenzaldehyde is not good, and the preservation and use need to be cautious.
Another method uses halogenated aromatics and thiourea as starting materials. First, the halogenated aromatics, such as 4-methylbenzyl chloride, react with thiourea under basic conditions to form intermediates, and then the intermediates are cyclized at high temperature to obtain the target. This way of raw materials is inexpensive, but there are many reaction steps, which require fine operation to ensure the purity and yield of the product.

I do not know the price range of 2- (4-methylphenyl) -1,3-benzothiazole in the market. The price of this product often varies due to various reasons, such as differences in quality, purchase quantity, purchase location, and market supply and demand. Or in the market of chemical raw materials, its price is determined by the cost of raw materials and the difficulty of production process; in the field of scientific research reagents, the quality and purity requirements are very high, and its price is also different.
