23 mg (0.90 mmol) of 95% sodium hydride were added at 0° C. to a solution of 163 mg (0.75 mmol) 4-(4-[1,2,3]triazol-1-yl-butyl)-phenol in 4.0 ml N,N-dimethylformamide and stirred for 30 min. at 0° C. 204 mg (0.75 mmol) 5-chloromethyl-2-(4-trifluoromethyl-phenyl)-pyridine (WO 2005/049573) were given to the reaction mixture and stirring continued at r.t for 2 days. After addition of 8 ml water the mixture was stirred for 1 h, the formed precipitate isolated by filtration, washed with water, methanol/water 1:1, and a small amount of ether. The residue was purified by chromatography on silica (eluent: ethyl acetate) to give 240 mg 71% of the title compound as white powder.
