Abstract:An improved method was designed to synthesize the Lornoxicam in overall yield of 56.3% from 5-chloro-3-chloro-2-thiophene sulfonyl carboxylate by the reactions of sulfonylation, cyclization and amidation. The structure of target compound was identified by 1H NMR. This method is more simple and environmentally friendly, and suitable for industrial production. |
Key words:Lornoxicam; sulfonylation; amidation; carboxylate |
