Procedure

To a stirred solution of methyl 1-({[4-(2-butynyloxy)phenyl]sulfonyl}amino)cyclopentane carboxylate (5.5 g, 15.6 mmol) in methanol:THF (4:1, 100 ml) 10 N sodium hydroxide (15 ml) was added at room temperature. It was stirred for 16 h and evaporated to dryness in vacuo, the residue was dissolved in 100 mL water, pH adjusted to 7 with 5N hydrochloric acid solution. It was extracted with chloroform;methanol (3:1) washed with water, dried and concentrated to give 1-({[4-(2- butynyloxy)phenyl]sulfonyl}amino)cyclopentane carboxylic acid. Yield 4.5 g (86%); White solid, mp.108-110° C. Electrospray Mass Spec 336 (M−H)−.
