153 mg of K2CO3 and 71 mg (1.0 mmol) of pyrrolidine were added to a solution of 387 mg (1.0 mmol) of 6-fluoro-2-(3-phenylpropylthio)-N-(thiophen-2-ylmethyl) -pyridine-3-carboxylic acid amide (exemplary compound 225) in DMF (10 ml), and the mixture was stirred for 2 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 7:3) of the residue yielded 308 mg (0.7 mmol, 71%) of 2-(3-phenyl-propylsulfanyl)-6-pyrrolidin-1-yl -N-(thiophen-2-yl-methyl)-pyridine-3-carboxylic acid amide. MS: m/z 438.2 [M+H]+.
