Yield:26116-12-1 86%

Reaction Conditions:

with 5%-palladium/activated carbon;ammonia;hydrogen at 95;Autoclave;

Steps:

4 Example 4 Preparation of 1-(1-ethylpyrrolidin-2-yl)methanamine
Take 60 g of Example 3 N-ethylpyrrole formaldehyde product into the autoclave,Add mass percent concentration of 5% palladium-carbon (5 g) and liquid ammonia 15 g,Hydrogenation and reductive amination under hydrogen pressure of 35 kg and 95°CAfter the reaction, cooling, exhaust, suction filtration, methanol washing,Methanol was recovered, and then the product N-ethyl-2-aminomethylpyrrole (53.7 g) was obtained by distillation under reduced pressure. The yield was 86%. The reaction equation was as follows:
