A mixture of 0.10 g (0.17 mmol) N-(3,5-bis-trifluoromethyl-benzyl)-6-(4-cyanomethyl-piperazin-1-yl)-N-methyl-4-o-tolyl-nicotinamide (Example 55), 34 mg (0.52 mmol) sodium azide and 36 mg (0.26 mmol) triethylammonium chloride in 1 ml 1-methyl-2-pyrrolidone was heated at reflux for 2 h. After cooling to room temperature 6 ml ice water were added. The mixture was acidified with 1N hydrochloric acid solution to pH 1-2 and extracted with dichloromethane. Drying of the combined extracts with sodium sulfate, concentration and flash column chromatography afforded 95 mg (88%) of the title compound as a light brown solid.
