To a solution of ethyl(2S)-2-ethoxy-3-(4-{2-[hexyl(2-phenylethyl)amino]-2-oxoethoxy}phenyl)propanoate (0.081 g, 0.17 mmol) in THF (8.6 mL) was added 4.3 mL of a 0.10 M LiOH solution and the reaction mixture was stirred at room temperature overnight. The reaction mixture was acidified with 2M HCl and extracted with ethyl acetate (3×25 mL). The combined organic phase was washed with brine (25 mL), dried over Na2SO4, and concentrated in vacuo to afford 0.073 g (96%) of a colourless oil.
