To a solution of 4-(morpholinomethyl)phenyl acetate (1.9 g, 8.1 mmol) in 1:1 methanol/water (40 mL) at 0° C. was added LiOH.H2O (339 mg, 8.1 mmol). The reaction was stirred at RT for 2 h. The mixture was concentrated to remove methanol, and the aqueous layer acidified with 3 N HCl. The aqueous layer was extracted with ethyl acetate (4×30 mL) and the organics dried and concentrated to give 454 mg recovered starting material. The aqueous layer was then made basic again (to pH 9) with 1 N NaOH and extracted with ethyl acetate (7×20 mL). These combined organics were washed with brine, dried with Na2SO4, and concentrated to give a white solid.
