An Efficient and Practical Process for the Synthesis of Glimepiride
A novel and simple approach to the synthesis of glimepiride is reported. It involves the preparation of a carbamate of 3-ethyl-4-methyl-1 H -pyrrol-2(5 H)-one, followed by its reaction with 4-(2-aminoethyl)benzenesulfonamide to produce the intermediate sulfonamide. This sulfonamide, upon reaction with phenyl (trans -4-methylcyclohexyl)carbamate, gave glimepiride. This process avoids the use of phosgene, isocyanates, or chloroformates. Furthermore, sulfonation of the aryl group was eliminated, rendering the product free of the impurities reported in earlier processes.
