Abstract
The sodium salt of [alpha] - aminobenzyl - penicillin is prepared by admixing anhydrous ampicillin with an excess of diethylamine in methylene chloride to form a solution of the diethylamine salt of ampicillin, admixing with said solution an approximately molar equivalent of sodium 2 - ethylhexanoate, admixing the resulting solution with substantially anhydrous acetonitrile and, after crystallization has occurred, separating the crystals which have formed. The temperature is 0 to 15 C. and the acetonitrile is added slowly with stirring e.g. at 0 + 1 C. Anhydrous ampicillin is prepared according to Specification 1,003,863. Specifications 873,049, 980,240, 1,060,034, 1,060,445 and 1,128,235 are referred to.
