Participants

Reaction Steps

To a solution of 0.273 g (0.840 mmol) of (2R)-2-[(4-but-2-ynyloxy-benzenesulfonyl)-methyl-amino]-propionic acid methyl ester in 6 mL of THF/methanol (1/1) was added 0.123 g (2.94 mmol) of lithium hydroxide monohydrate and the resulting solution was stirred at room temperature for 3 h. The reaction was then acidified with 5% HCl solution and extracted with chloroform. The combined organics were dried over MgSO4, filtered and concentrated in vacuo to give 0.256 g of 2-[(4-but-2-ynyloxy-benzenesulfonyl)-methyl-amino]-propionic acid as a white solid.
