Procedure
An aqueous solution of 10% sodium hydroxide (65 ml., 0.1625 mole) is slowly added to a suspension of N-[3-(mercaptoacetylamino)benzoyl]glycine (43 g., 0.16 mole) in 230 ml. of tetrahydrofuran with cooling at 10°-20° C. The mixture is warmed to about 20°-25° C. and filtered from a trace of solid. Diluting the filtrate with 480 ml. of tetrahydrofuran promotes the formation of a suspension which is stirred for 2 hr. and collected. The collected material is washed with tetrahydrofuran and air dried to provide 50 g. (88.3% yield) of N-[3-(mercaptoacetylamino)benzoyl]glycine sodium salt hydrated with 3.5 moles water, m.p. 68°-120° C. (dec.).
