Procedure

(2S)-3-{4-[4-(4-Benzoyl-phenoxy)-but-1-ynyl]-phenyl}-2-methoxy-propionic acid from Example 42, (1 eq) was mixed with Hydroxylamine chlorydrate (4 eq), pyrydine (10 eq) and Ethanol (2 ml) and the mixture reaction was stirred overnight. The ethanol was evaporated under vacuo and HCl 0.5% was added to the residue to pH=3. Extracted with Ethyl Acetate and concentrated to give the title product as a mixture of two oximes. MS (ES) for C27H25NO5 [M+H]+: 444.2.
