To prepare Ethyl 3 - hydroxy - 6 - (trifluoromethyl) pyridine - 2 - carboxylate, follow the following ancient method.
First, use a pyridine derivative containing a specific substituent as the starting material. Choose a suitable pyridine substrate with a transformable group at the corresponding position, and it needs to be stable for subsequent reaction conditions. In a suitable reactor, add this pyridine derivative, and then add an appropriate amount of base, such as potassium carbonate or sodium carbonate, to create an alkaline environment. Subsequently, a trifluoromethyl-containing reagent, such as trifluoromethyl halide, is added dropwise. In this basic system, the halide undergoes a nucleophilic substitution reaction with the pyridine substrate, and trifluoromethyl is introduced at a specific position in the pyridine ring.
Second, after the successful introduction of trifluoromethyl, another position on the pyridine ring is hydroxylated. This step can be achieved by means of oxidation reaction. Select an appropriate oxidizing agent, such as hydrogen peroxide or m-chloroperoxybenzoic acid, and under mild reaction conditions, oxidize the specific carbon-hydrogen bonds on the pyridine ring to generate hydroxyl groups. During operation, the reaction temperature and time need to be carefully adjusted to prevent excessive oxidation.
Third, construct the structure of carboxyl ethyl ester. The product of the above two-step reaction is co-placed in a reaction vessel with ethanol and an appropriate amount of catalyst, such as concentrated sulfuric acid or p-toluenesulfonic acid, and heated for esterification. This reaction needs to be carried out under a reflux device to maintain a suitable temperature for the reaction system to promote the esterification of carboxylic acid and ethanol, so as to form a carboxyl ethyl ester structure at a specific position in the pyridine ring.
During the entire synthesis process, each step of the reaction needs to be separated and purified. Column chromatography, recrystallization and other means can be used to obtain high-purity Ethyl 3-hydroxy-6- (trifluoromethyl) pyridine-2-carboxylate products. And the reaction conditions of each step need to be carefully controlled to improve the yield and purity of the product.

I have not heard that there is a price of "Ethyl+3-hydroxy-6-%28trifluoromethyl%29pyridine-2-carboxylate" in the market, but if you want to measure the range of its price, you can think of all kinds of clues.
This compound has a unique chemical structure and contains groups such as trifluoromethyl and ethyl pyridine carboxylate. The synthesis method may be more complicated, and the materials used may be expensive. During synthesis, the price of the starting materials, reagents and catalysts used has a great impact on the final selling price. If the starting materials are rare and hard to find, the price will be high. For example, some pyridine derivatives with special substituents can cost tens of gold per gram, or even hundreds of gold.
The reaction conditions are also critical. If harsh temperature, pressure or inert gas protection is required, energy consumption and operating costs will increase significantly. If it needs to be reacted under high temperature and high pressure, the equipment input and energy consumption are large, the cost rises, and the product price is also high.
Its purity requirements also affect the price. If used in high-end fields such as medicine and electronics, extremely high purity is required, and the purification cost is high. Fine chemicals with a purity of more than 99% may be several times or even dozens of times higher than ordinary purity.
In addition, market supply and demand are also the main reasons. If there are many people who want it, but there are few products, the price will rise; if the supply exceeds the demand, the price may drop.
From a comprehensive perspective, if it is a "Ethyl+3-hydroxy-6-%28trifluoromethyl%29pyridine-2-carboxylate" of laboratory grade and ordinary purity, the price per gram may be between tens of yuan and hundreds of yuan; if it is a high purity and suitable for high-end industries, the price per gram may exceed 1,000 yuan, or even higher. However, these are all numbers, and the actual price still needs to be carefully inspected by the market and suppliers.
