Synthesis and Antimicrobial Activities of 1-((5-Chloro-1-ethyl-2-methyl-1H-imidazol-4-yl)sulfonyl)-N-ethylpyrrolidine-2-carboxamide

A new 1-((5-chloro-1-ethyl-2-methyl-1H-imidazol-4-yl)sulfonyl)-N-ethylpyrrolidine-2-carboxamide was synthesized from methyl-1-[(5-chloro-1-ethyl-2-methyl-1H-imidazol-4-yl)sulfonyl]pyrrolidine-2-carboxylate and ethylamine. The compound methyl-1-[(5-chloro-1-ethyl-2-methyl-1H-imidazol-4-yl)sulfonyl]pyrrolidine-2-carboxylate was synthesized from methyl pyrrolidine-2-carboxylate and 5-chloro-4-chlorosulfonyl-1-ethyl-2-methyl-imidazole. The compounds were characterized based on FTIR, 1H, 13C NMR, and DEPT 135 analysis. Antimicrobial activities of the 1-((5-chloro-1-ethyl-2-methyl-1H-imidazol-4-yl)sulfonyl)-N-ethylpyrrolidine-2-carboxamide against Gram-positive (methicillin-susceptible Staphylococcus aureus, methicillin-resistant Staphylococcus aureus, and Bacillus subtilis), Gram-negative (Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumoniae), and Candida albicans were carried out using the standard microbiological method. The newly synthesized 1-((5-chloro-1-ethyl-2-methyl-1H-imidazol-4-yl)sulfonyl)-N-ethylpyrrolidine-2-carboxamide had no activities against the tested organisms.
