Procedure

A mixture of 0.35 ml (3.7 mmol) acetic anhydride and 0.17 ml (4.6 mmol) formic acid was heated at 50° C. for 2 h. After cooling to room temperature a portion of 0.08 ml of this mixture was added to 0.5 ml THF. A solution of 0.10 g (0.14 mmol) (S)-N-[6-(2-benzyloxymethyl-piperazin-1-yl)-4-(4-fluoro-2-methyl-phenyl)-pyridin-3-yl]-2-(3,5-bis-trifluoromethyl-phenyl)-N-methyl-isobutyramide (Example 383a)) in 1 ml THF was added dropwise at 0° C. Conversion was monitored by thin layer chromatography. After complete consumption of the starting material the reaction mixture was diluted with water and extracted with three portions of dichloromethane. The combined organic extracts were dried over sodium sulfate and concentrated in vacuo to give 0.11 g of crude (S)-N-[6-(2-benzyloxymethyl-4-formyl-piperazin-1-yl)-4-(4-fluoro-2-methyl-phenyl)-pyridin-3-yl]-2-(3,5-bis-trifluoromethyl-phenyl)-N-methyl-isobutyramide as a light yellow solid.
