Summary:The present invention relates to a novel, cost-effective process for the preparation of Sterile Meropenem Trihydrate, which is prepared by a) condensation of l-Azabicyclo[3.2.0]hepta-2-ene-2-carboxylic acid, 3- [(diphenoxyphosphinyl)oxy]-6-(l-hydroxyethyl)-4-methyl-7-oxo-(4-nitrobenzyl) methyl ester,[4R-[4a,5b,6b(R*)]] with (2S,4S)-2-(Dimethylaminqcarbonyl)-4- mercapto-l -(p-nitrobenzyloxycarbonyl)-l -pyrrolidine to obtain diprotected Meropenem; b) deprotection and hydrogenation of diprotected Meropenem to obtain non-sterile Meropenem Trihydrate; c) conversion of NS Meropenem Trihydrate into Sterile Meropenem Trihydrate by using water, methanolic ammonia solution and purging carbon dioxide gas. La présente invention porte sur un nouveau procédé rentable de préparation de trihydrate de Meropenem stérile, qui est préparé par : a) condensation d'acide l-Azabicyclo[3.2.0]hepta-2-ène-2-carboxylique, de 3- [(diphénoxyphosphinyl)oxy]-6-(l-hydroxyéthyl)-4-méthyl-7-oxo-(4-nitrobenzyl)méthylester, [4R-[4a,5b,6b(R*)]] avec (2S,4S)-2-(Diméthylaminocarbonyl)-4- mercapto-l -(p-nitrobenzyloxycarbonyl)-l -pyrrolidine en vue de l'obtention de Meropenem diprotégé; b) déprotection et hydrogénation de Meropenem diprotégé en vue de l'obtention de trihydrate de Meropenem non stérile; c) conversion de trihydrate de Meropenem NS en trihydrate de Meropenem stérile à l'aide d'eau, d'une solution d'ammoniac méthanolique et de dioxyde de carbone gazeux de purge.
