2 - (4 -Aminophenyl) -6 -methylbenzothiazole, this substance has a rather specific property. Its shape or crystalline state, the color is white to yellowish, and it seems to have a warm luster. It looks like fine silt, flickering slightly in the sun, just like hiding shimmer.
When it comes to the degree of melting, at a certain temperature range, when heated to a certain point, it will gradually melt from the solid state, just like spring ice when it is warm, slowly turning invisible. Its solubility in various solvents is also unique. In organic solvents such as ethanol, it is slightly soluble, just like a drizzle entering a lake. Although it can disperse a little, it is difficult to form a uniform state; in strong polar solvents, such as dimethyl sulfoxide, it has good solubility and can be fused into one, just like water and milk.
Its stability is also considerable. Under room temperature and pressure, it can maintain its inherent state for a long time, just like the safety of a rock. When it encounters a hot topic or an open flame, it is like a lying firewood, which can easily cause combustion or even the risk of explosion. Therefore, when it is stored, it should be avoided.
And it has a certain toxicity. Although it has not reached a highly toxic state, it will also endanger physical health if it is accidentally touched, smelled or eaten. If it touches the skin, it may cause redness, swelling and itching; if it enters the mouth and nose, it may disturb the ability to breathe and stomach, so when using it, be extra cautious to ensure safety.

2 - (4 -Aminophenyl) -6 -methylbenzothiazole, this is an organic compound with unique chemical properties.

Then, add an appropriate amount of acid binding agent, such as potassium carbonate or triethylamine, to neutralize the acid generated by the reaction and promote the positive reaction. The reaction system is heated to a moderate temperature, about 60-80 ° C, and stirred continuously. This temperature range is conducive to the reaction and can avoid excessive side reactions. During the reaction, pay close attention to the reaction process, which can be monitored by thin layer chromatography (TLC). When the raw material point is basically eliminated, it means that the reaction is almost complete.
After the reaction is completed, the reaction solution is cooled to room temperature, then poured into an appropriate amount of water, and the product is extracted with an organic solvent, such as ethyl acetate, and extracted several times to improve the yield. The organic phases are combined, washed with saturated saline water, and dried with anhydrous sodium sulfate to remove the residual water in the organic phase. After that, the organic solvent is removed by reduced pressure distillation to obtain a crude product. < Br > Then the crude product is purified by column chromatography, silica gel is used as the stationary phase, and a suitable eluent is selected, such as a solution of petroleum ether and ethyl acetate mixed in a certain proportion, and the proportion is determined by experiment according to the properties of the product. The eluent containing the pure product is collected and the solvent is evaporated to obtain pure 2- (4-aminophenyl) -6-methylbenzothiazole. This process requires fine operation and proper control of each step condition to obtain the ideal product.
