Procedure
A solution of 0.764 g (1.41 mmol) of methyl4-{[4-({6-[(tert-butoxycarbonyl)amino]-2-hexynyl}oxy)phenyl]sulfonyl}-2,2-dimethyl-3-thiomorpholinecarboxylate and 3.77 g (28.2 mmol) of lithium iodide in 30 mL of ethyl acetate was heated to reflux for 18h. The resulting reaction was acidified, washed with water, an aqueous solution of Na2S2O3 , brine, dried over MgSO4, filtered and concentrated in vacuo. The residue was chromatographed on silica gel eluting with 0.5% methanol/dichloromethane to provide 0.417 g (56%) of 4-{[4-({6-[(tert-butoxycarbonyl)amino]-2-hexynyl}oxy)phenyl]sulfonyl}-2,2-dimethyl-3-thiomorpholine carboxylic acid as a white solid. Electrospray Mass Spec: 527.2(M+H)+
