To prepare 2,5-dichloro-3-pyridine methanol, the method is as follows:
First, an appropriate pyridine compound is taken as the starting material. The 3, 2 and 5 positions of the pyridine ring in the raw material structure should have modifiable groups. Usually, 2,5-dichloropyridine is used as the starting material, because there are chlorine atoms in the 2 and 5 positions, only the methanol group needs to be introduced at the 3 position.
Variants of the halogenation reaction can be used to replace the 3 position of the pyridine ring. For example, a suitable metal reagent, such as an organolithium reagent or a Grignard reagent, interacts with 2,5-dichloropyridine. The organolithium reagent has high activity. When reacting with 2,5-dichloropyridine, lithium atoms can replace the hydrogen atoms at the 3 position of the pyridine ring to form an active intermediate. Subsequently, a suitable source of formaldehyde is added to this reaction system, such as paraformaldehyde or formaldehyde aqueous solution. The active intermediate reacts with formaldehyde and introduces hydroxymethyl groups at the 3 position of the pyridine ring. After subsequent treatment such as hydrolysis, 2,5-dichloro-3-pyridine methanol can be obtained.
Or a coupling reaction catalyzed by transition metals. Using 2,5-dichloropyridine as the substrate, a transition metal catalyst with a suitable ligand is selected, such as a palladium catalyst. At the same time, a reagent containing methanol group with suitable leaving group was selected. Under suitable alkali and reaction conditions, the coupling of the 3-position of the pyridine ring with the methanol group was realized through the steps of oxidative addition, migration insertion, reduction and elimination, and then the target product 2,5-dichloro-3-pyridine methanol was obtained. The reaction process requires strict control of the reaction temperature, reaction time and the ratio of each reactant to achieve higher yield and selectivity.

2 + - 3 - pyridyl methanol, 2,5 - dichloro - This material involves many safety precautions and must be treated with caution.
First, fire prevention is essential. Because of its flammability, it is necessary to keep away from open flames and hot topics in use and storage places, such as stoves and welding equipment. Lighting fixtures also need to be explosion-proof, and electrical equipment must be well grounded to prevent static electricity from causing fires.
Second, leakage prevention cannot be ignored. When operating, be careful to prevent leakage due to damage to the container. In the event of leakage, quickly evacuate unrelated personnel to a safe area, and strictly prohibit fire. Emergency responders need protective clothing and gas masks, first cut off the source of leakage, and then choose the treatment method according to the amount of leakage. A small amount of leakage can be absorbed by inert materials such as sand and vermiculite; a large amount of leakage needs to be embanketed and contained before treatment.
Third, it is related to human protection. When coming into contact with this object, complete protective measures must be taken. Wear protective glasses during operation to avoid splashing into the eyes and damaging eye tissue; wear protective clothing to prevent skin contact to prevent irritation or absorption of poisoning; wear a gas mask, if in a high concentration environment, you need to use a full mask respirator to avoid inhaling harmful substances and damaging the respiratory tract.
Fourth, storage is also exquisite. It should be stored in a cool and well-ventilated place, away from fire and heat sources. Store separately from oxidants, acids, etc., and should not be mixed. The storage area should be equipped with suitable materials to contain leaks.
In short, when dealing with 2-3-pyridyl methanol, 2,5-dichloro-need to be vigilant at all times and strictly abide by safety procedures to ensure safe operation and avoid accidents.
