919 mg (6.0 mmol) of K2CO3 and 305 mg (2.0 mmol) of 3-phenylpropane-1-thiol were added to a solution of 509 mg (2.0 mmol) of 2,6-difluoro-N-(thiophen-2-ylmethyl)-nicotinamide in DMF (10 ml), and the mixture was stirred for 1 h at RT. Dilution with water and extraction with EA were then carried out. The organic phase was washed with water and brine, dried over Na2SO4, filtered and concentrated in vacuo. CC (hexane/EA 4:1) of the residue yielded 336 mg (0.9 mmol, 43%) of 6-fluoro-2-(3-phenylpropylthio)-N-(thiophen-2-ylmethyl)pyridine-3-carboxylic acid amide. MS: m/z 387.1 [M+H]+.
