What is the synthesis method of 1- (3-iodophenyl) methanamine Hydrochloride?
The synthesis of 1 - (3 - iodophenyl) methylamine hydrochloride is an important task in the field of organic synthesis. There are many methods, which can be selected according to the existing raw materials and reaction conditions.
One method may be initiated by 3 - iodobenzaldehyde. Shilling 3 - iodobenzaldehyde reacts with ammonia or ammonia derivatives, such as ammonium acetate, etc. This reaction often requires a suitable solvent, such as an alcohol solvent, adding a reducing agent, such as sodium borohydride or sodium cyanoborohydride. Sodium borohydride has strong reducing properties, and the resulting imine intermediates can be efficiently reduced to amines in the reaction system to obtain 1 - (3 - iodophenyl) methylamine. Thereafter, the target product 1 - (3 - iodophenyl) methylamine hydrochloride is obtained by acidifying the amine with hydrochloric acid.
Furthermore, 3 - iodobenzyl halide can also be used as a raw material. The 3 - iodobenzyl halide and nucleophiles, such as sodium azide, undergo a nucleophilic substitution reaction to generate 3 - iodobenzyl azide. Subsequently, through the reduction step, the azide group can be reduced to an amino group by catalytic hydrogenation, using palladium carbon as a catalyst and hydrogen as a reducing agent to obtain 1 - (3 - iodophenyl) methylamine. Finally, the same treatment with hydrochloric acid is used to form hydrochloride.
Or with 3-iodobenzoic acid as the starting material. First convert it into an acid chloride, such as reacting with dichlorosulfoxide. Then react the acid chloride with ammonia to obtain an amide. Then, through the Hoffmann degradation reaction, react with bromine or chlorine under alkaline conditions, and the amide is converted into an amine with one less carbon atom, namely 1 - (3-iodophenyl) methylamine, and finally acidify to obtain hydrochloride.
Each method has its own advantages and disadvantages. In actual synthesis, factors such as the availability of raw materials, cost, difficulty in controlling reaction conditions, yield and purity must be considered, and careful choices must be made to achieve the purpose of efficient preparation of 1- (3-iodophenyl) methylamine hydrochloride.
