Procedure
In 1.4 ml of ethanol was dissolved 0.31 g of 4-[2-(carboxymethyl)-3-oxo-4-phenethyl-1-thia-4,8-diazaspiro[4.5]decan-8-yl]-4-oxobutanoic acid. After adding 1.36 ml of 1 mol/L aqueous solution of sodium hydroxide at 0-5° C., the resulting mixture was stirred at ambient temperature for 5 hours. The reaction mixture was poured into a mixture of ice water and ethyl acetate, and the aqueous layer was separated. The aqueous layer thus obtained was concentrated under reduce pressure to obtain 0.32 g of disodium 4-[2-(carboxymethyl)-3-oxo-4-phenethyl-1-thia-4,8-diazaspiro[4.5]decan-8-yl]-4-oxobutanoate as a colorless solid product.
