Reaction Steps

This ester was reacted with excess methanolic lithium hydroxide at room temperature, followed by evaporation of the methanol. The residue was dissolved in water and acidified with 2N hydrochloric acid to give 2-[{[4-(2-butynyloxy)phenyl]sulfonyl}(methyl)amino]-2-(4-chlorophenyl)acetic acid as colorless crystals, mp 170-172° C., Electrospray Mass Spec 406.4 (M−H)−.
