Procedure

5-{4-[5-(2-Chloro-4-methoxyphenyl)-1-methyl-1-H-1,2,4-triazol-3-yl]bicyclo[2.2.2]oct-1-yl}pentan-2-ol (5-J) (0.036 g, 0.086 mmol) was placed in a small vial with 0.5 mL of DMF. Sodium ethanethiolate (0.0218 g, 0.260 mmol) was added to the solution. The vial was sealed and heated to 100° C. for 1.5 h. The incomplete reaction required another 1.5 equivalents of sodium ethanethiolate (0.011 g). The vial was resealed and heated at 100° C. for 1 h. The product, 3-chloro-4-{5-[4-(4-hydroxypentyl)bicyclo[2.2.2]oct-1-yl]-1-methyl-1-H-1,2,4-triazol-3-yl}phenol (5-K) was purified by preparative reverse phase HPLC on a C-18 silica gel column using a gradient of acetonitrile-water buffered with 0.1% trifluoroacetic acid. The effluent containing the pure triazole was made basic with 10% NaHCO3, evaporated in vacuo to remove most of the acetonitrile, and extracted with methylene chloride. The organic extract was dried (MgSO4) and evaporated, and the residue dried under vacuum to provide the desired compound. MS (ESI+)=404.4 (M+1).
