How is 1-Ethylpyrrolidine (CAS: 7335-06-0) typically synthesized?

1-Ethylpyrrolidine is commonly synthesized through the reaction of ethylamine with pyrrolidone in an aqueous medium using a base like sodium hydroxide. The process involves aromatic substitution and is known for its good yield and selectivity. Common catalysts include basic catalysts, and the reaction is typically carried out under mild conditions to ensure high purity of the product.
