553 mg (4 mmol) of K2CO3 and 268 mg (1.0 mmol) of 3,3-difluoro-3-(4-fluorophenyl)-propyl methanesulfonate were added in succession to a solution of 262 mg (1.0 mmol) of N-(bicyclo[2.2.1]heptan-2-ylmethyl)-2-mercapto-nicotinamide in DMF (3 ml), and the mixture was heated for 3 h at 60° C. Dilution with water and extraction with EA were then carried out. The organic phase was washed with brine, dried over Na2SO4, filtered and concentrated in vacuo. CC (hexane/EA 7:3) of the residue yielded 229 mg (0.5 mmol, 53%) of N-(5-bicyclo[2.2.1]heptanyl-methyl)-2-[[3,3-difluoro-3-(4-fluoro-phenyl)-propyl]sulfanyl]-pyridine-3-carboxylic acid amide. MS: m/z 435.2 [M+H]+.
