If you want to prepare 2-pyridyl methanol, 3,5-dimethyl, you can do it according to the following method.
First, use 3,5-dimethyl pyridine as the starting material. First, it is added to formaldehyde and hydrocyanic acid. This step needs to be carried out under appropriate catalysts and mild reaction conditions to obtain the corresponding cyanyl compound. Then the obtained cyanyl compound is hydrolyzed with suitable reagents, such as acid or base catalyzed hydrolysis, and the product of 2-pyridyl methanol and 3,5-dimethyl can be obtained. Although this path is a little complicated, the raw material is relatively easy to find, and the reaction conditions of each step are relatively mild and easy to control. < Br >
Second, a suitable halopyridine derivative is used as the starting material. If there is a halopyridine containing a suitable halogen atom at the 2-position and the 3,5-position is methyl, it can be reacted with nucleophiles such as methanol salts in an organic solvent. This reaction needs to be carried out at an appropriate temperature and reaction time, and the halogen atom is replaced by a methoxy group. After the reduction step, the methoxy group can be converted into a hydroxymethyl group to obtain the target product. The key to this method is the selection and preparation of halopyridine derivatives, and the reduction step needs to select the appropriate reducing agent and conditions to obtain a high-purity product.
Third, you can try the reaction with organometallic reagents. For example, the coupling reaction between 3,5-dimethyl-2-pyridyl boronic acid and a suitable halogenated methanol derivative is carried out in the presence of a palladium catalyst, under the action of a suitable solvent and base. This reaction can efficiently construct the structure of the target product, but the price of palladium catalyst is higher, the requirements for reaction equipment and operation are also higher, and the cost is relatively large.
The above methods have their own advantages and disadvantages. In actual preparation, the appropriate synthesis path should be carefully selected according to the availability of raw materials, cost considerations, product purity requirements and other factors.

2-Pyridyl methanol, 3,5-dimethyl, when using, many matters need to be paid attention to. This substance has specific chemical properties. For its storage, it must be placed in a cool, dry and well-ventilated place, away from fires and heat sources. Because it may be flammable, it can cause combustion in case of open flames and hot topics, so fire prevention is the top priority.
Furthermore, when operating, it is necessary to strictly observe safety procedures. It is advisable to wear suitable protective equipment, such as protective gloves, goggles, etc., to prevent the substance from contacting the skin and eyes. Because it may cause irritation to the human body, if it is inadvertently touched, it should be rinsed with plenty of water immediately and seek medical treatment as appropriate.
In terms of the use environment, ensure that the place is well ventilated to avoid the accumulation of its vapor. Because the vapor reaches a certain concentration in the air, there may be a risk of explosion. At the same time, the use process should accurately control the dosage, take it according to actual needs, avoid waste, and prevent it from flowing into the environment, so as not to cause harm to the surrounding ecology.
In addition, the utensils that come into contact with it should be properly cleaned after use to prevent residual substances from affecting subsequent operations or causing adverse consequences such as corrosion. In short, be careful and follow various norms to use this substance safely and effectively.
