Abstract

Procedure for the peparation of a solution of a 7-aminocephalosporanic acid (certificate of addition of the patent of invention number 497076). A suspension of a 1-aminocephalosporanic acid with a selected biciclica amidina of among 1-diazabiciclo (4,3,0) non-5-eno, 1,8-diabiciclo (5,4,0) undec is reacted -7-eno and similar, in a selected organic solvent of between methanol, isopropanol, dichloromethane, 1,2-dichloroethane and similar, and a temperature of -20 to 0 centigred degrees, to obtain a solution of a salt of the acid 7- aminocephalosporanico, addionandose a salt of tertiary amine, such as trietilamine, and a carboxilic acid, such as the trimethylaceic, 2-ethylhexanoic and similar, to obtain a useful solution for its last reaction with the active form of a carboxylic acid.
