Versuchsvorschrift

To a vial was added 2-bromo-4-(5-chloropyridin-3-yl)-3-[(trans-4-methylcyclohexyl)methyl]-3H-imidazo[4,5-c]pyridine-6-carbonitrile (Preparative Example 3.1, 382.2 mg, 0.86 mmol), (S)-2-(fluoromethyl)pyrrolidine hydrochloride (240 mg, 1.72 mmol), potassium fluoride (250 mg, 4.30 mmol), DMSO (2.6 mL), and N,N-diisopropylethylamine (0.75 mL, 4.30 mmol). The vial was sealed and heated to 100° C. for 16 hours. The reaction mixture was cooled to room temperature, diluted with ethyl acetate, and washed with water and then brine. The organic layer was dried over sodium sulfate, filtered, and concentrated under reduced pressure. The residue was purified by silica gel chromatography (0-100% ethyl acetate/hexanes, linear gradient) to afford 4-(5-chloropyridin-3-yl)-2-[(2S)-2-(fluoromethyl)pyrrolidin-1-yl]-3-[(trans-4-methylcyclohexyl)methyl]-3H-imidazo[4,5-c]pyridine-6-carbonitrile. MS ESI calc'd. for C25H28ClFN6 [M+H]+ 467. found 467.
