実験手順

A solution of 4-([4-(2-butynyloxy)phenyl]sulfonyl}-morpholine-3-carboxylic acid, methyl ester (0.1 g, 0.28 mmol) in 2.4 mL of THF:methanol:water [4:1:1]was cooled in an ice bath and 2N LiOH (0.3 mL, 0.59 mmol) was added. The reaction was stirred at 0° C. for 30 minutes and at room temperature for 2 hours. After evaporating the solvent, the residue was diluted with ether and filtered. The solid was dissolved in water, neutralized with 1N HCl to pH˜3 and extracted with dichloromethane. The organic layer was washed with water and brine, dried over sodium sulfate, filtered and concentrated to give 0.06 g of 4-([4-(2-butynyloxy)phenyl]sulfonyl}-morpholine-3-carboxylic acid. Yield˜69.8%. mp 40-42° C. Electrospray Mass Spec 338.1(M−H)−.
