Procedure

To a solution of 0.20 g (0.33 mmol) (S)-2-(3,5-bis-trifluoromethyl-phenyl)-N-[4-(4-fluoro-2-methyl-phenyl)-6-(2-hydroxymethyl-pyrrolidin-1-yl)-pyridin-3-yl]-N-methyl-isobutyramide and 54 mg (0.37 mmol) phthalimide in 3 ml tetrahydrofuran were added 71 mg (0.37 mmol) diethyl azodicarboxylate (90%) and 97 mg (0.37 mmol) triphenylphosphine at 0° C. After stirring for 90 min. the reaction mixture was allowed to warm to room temperature over night. The mixture was diluted with a 0.1 M aqueous sodium hydroxide solution and extracted with three portions of tert-butyl methyl ether. The combined organic extracts were dried over sodium sulphate and concentrated. Flash column chromatography gave 70 mg (29%) of the title compound as a light yellow solid.
