To prepare a-phenyl-2-pyridyl methanol, there are various methods. First, it can be obtained from the Grignard reaction of 2-pyridyl formaldehyde and phenyl magnesium halide. First, prepare phenyl magnesium halide, use magnesium and halogenated benzene in anhydrous ethyl ether to initiate a reaction. When the magnesium chips gradually dissolve, the solution becomes muddy and bubbles escape. This is phenyl magnesium halide. Then, at low temperature, the ether solution of 2-pyridyl formaldehyde is slowly dripped into the phenyl magnesium halide solution, dripped, heated and refluxed to make the reaction sufficient. After the reaction is stopped, hydrolysis with dilute acid, and then extraction, drying, distillation and other steps, the product can be obtained. < Br >
Second, 2-pyridinecarboxylate can also be used to react with phenyllithium. First, phenyllithium is prepared, and lithium is reacted with halobenzene in anhydrous ether or tetrahydrofuran at low temperature. After forming phenyllithium, the solution of 2-pyridinecarboxylate is slowly added to it. After appropriate reaction time and conditions, and then post-treatment, such as hydrolysis, separation, and purification, a-phenyl-2-pyridinecarboxylic alcohol is also obtained.
Third, catalytic hydrogenation is also possible. Using 2-pyridinecarboxylate as a raw material, hydrogenation in a hydrogen atmosphere in the presence of a suitable catalyst such as palladium carbon. Control temperature, pressure and other conditions to reduce the carbonyl group to a hydroxyl group to obtain the target product. This process requires attention to catalyst activity, dosage and reaction conditions to achieve the best yield. All production methods have their own advantages and disadvantages, and must be used according to the actual situation, such as the availability of raw materials, cost, and difficulty of reaction conditions.

A-phenyl-2-pyridyl methanol is also an organic compound. When storing and transporting, many matters must be paid attention to.
