Abstract

Procedure for the obtaining of the phthalide ester of the acid 6 (d (-) - alpha-aminofenilacetamido) penicilanico and its organic or inorganic salts.- characterized in that it consists of reacting in organic or aqueous-organic medium the sodium salt of the acid 6 ( N-methylene-d (-) - alpha-amino phenyl acetamido) penicillanic acid with a 3-sulfonate of phthalide at temperatures between -10 and 40ºC isolating the product obtained by evaporation of the solvent or precipitation and subsequent acid hydrolysis with organic or inorganic acids to obtain the salts of the ester with subsequent neutralization with organic or inorganic bases to obtain the ester according to the following reaction scheme: ** (formula-01) ** ** (formula-02) ** ** (formula-03) ** ** (formula-04) ** (Machine-translation by Google Translate, not legally binding)
