Procedure

A mixture of methyl [{[4-(2-butynyloxy)phenyl]sulfonyl}(methyl)amino}(4-{3-[(ethoxycarbonyl)amino]propoxy]phenyl)acetate (0.45 g, 0.85 mmol) and 1N NaOH (4.2 ml, 4.23 mmol) in THF (5 ml) and methanol (5 ml) was stirred at room temperature for 2 h. After removing the solvent, the residue was dissolved in water, neutralized with HCl to pH˜5-6 and extracted with dichloromethane. The organic layer was washed with water and brine, dried over sodium sulfate, filtered and concentrated to provide 0.36 g of [{[4-(2-butynyloxy)phenyl]-sulfonyl}(methyl)amino}(4-{3-[(ethoxycarbonyl) amino]propoxy]phenyl)acetic acid as a solid . Yield 81.8%. Electrospray Mass Spec 519.1 (M+H)+.
