Reaction Steps

To a solution of 6-chloro-4-[(6-methylpyridin-2-yl)amino]pyridine-3-carbonitrile (PrepEx 1.3) (38 mg, 0.16 mmol) in NMP (1 mL) was added butane-1,2-diamine (107 mg, 1.21 mmol) and N,N-diisopropylethylamine (0.163 mL, 0.932 mmol). The reaction mixture was heated to 100° C. After 16 hours, the reaction mixture was allowed to cool to room temperature, filtered, and purified directly via reverse phase HPLC (acetonitrile/water with 0.1% TFA, linear gradient) to afford 6-[(2-aminobutyl)amino]-4-[(6-methylpyridin-2-yl)amino]pyridine-3-carbonitrile. MS ESI calc'd. for C16H21N6 [M+H]+ 297. found 297.
