** 1.2-Hydroxy-2-methylpropionitrile Synthesis **
To prepare 2 - (2-hydroxyethyl) pyridine, 2-hydroxy-2-methylpropionitrile can be used. First, 2-hydroxy-2-methylpropionitrile and the corresponding pyridine derivative are reacted under suitable catalysts and specific reaction conditions. This reaction requires delicate control of temperature, pressure and reactant ratio. Usually, when heated gently and in the presence of suitable basic catalysts, a series of reactions such as nucleophilic substitution can occur between the two. During the

. Acrylonitrile is first hydrolyzed, and under acidic or basic conditions, the nitrile group is converted into carboxyl or amide groups that can be further reacted. After that, the product and pyridine derivatives undergo condensation reaction under the action of condensation agent and catalyst.
During the condensation process, the catalyst activity check point guides the reaction direction to ensure that the reaction proceeds according to the predetermined path and forms a key intermediate. The intermediate is then carefully modified by subsequent reaction steps such as reduction and substitution, and gradually approaches the target structure of 2- (2-hydroxyethyl) pyridine. After each step of reaction, it is necessary to properly separate and purify to ensure the purity of the raw materials in the next step and improve the yield and purity of the final product. < Br >
