Procedure

A suspension of 294.78 mg. of 7-[2-(4-ethyl-2,3-dioxo-1-piperazinecarboxamido)-2-(p-hydroxyphenyl)acetamido]-3-(hydroxymethyl)-8-oxo-5-thia-1-azabicyclo[4.2.0]-oct-2-ene-2-carboxylic acid, 3-acetate and 136.6 mg. of 4-amino-5-(1-pyrazolyl)-4H-1,2,4-triazole-3-thiol in 10 ml. of water is adjusted to pH 6.5 with an aqueous solution of sodium bicarbonate. A 5 ml. portion of acetone is added producing solution. This solution is stirred at 60°-63° C. for 5 hours, then stripped free of acetone under reduced pressure, cooled to room temperature and filtered. The filtrate is acidified to pH 2.0 with 2 N hydrochloric acid. The resulting solid is filtered and dried giving 192 mg. of the desired product.
