Process for preparing an alpha-aminobenoylpegalilin, characterized in that a solution of 6-aminopenicillanic acid or its water soluble salt, is dissolved to form a first solution; the solid contaminants are separated from the first solution; a second solution is formed by dissolving a mixed anhydride acylating agent in an organic solvent; the second solution is cooled to a temperature of about -50ºC or less; the solid contaminants are separated from the second cooled solution; and the two solutions are combined for their reaction and production of the desired α-aminobenzo-penicillin.
