Reaction Steps

To a solution of 2-(6-tert-butoxycarbonylamino-pyridin-3-ylmethyl)-3-[hydroxy-(3-phenyl-propyl)-phosphinoyl]-propionic acid ethyl ester (0.240 g 0.489 mmol) in MeCN (3 mL) was added a solution of LiOH (0.059 g 2.45 mmol) in H2O (3 mL). The mixture was then stirred at 20° C. for 1.5 hours. Ethylacetate was added and the mixture was washed with 1 M HCL and brine and filtered to give 2-(6-tert-butoxycarbonylamino-pyridin-3-ylmethyl)-3-[hydroxy-(3-phenyl-propyl)-phosphinoyl]-propionic acid (0.174 g, 77%) as white crystals.
