A mixture of 2-(dimethylamino)acetic acid (6.05 mg, 0.059 mmol), NMP (0.5 ml), Huenig's Base (0.023 ml, 0.132 mmol), and HATU (24.55 mg, 0.065 mmol) was stirred at ambient temperature for 5 minutes, followed by addition of N2′-(trans-4-aminocyclohexyl)-5′-chloro-N6-(3-fluorobenzyl)-2,4′-bipyridine-2′,6-diamine (Example 1) (12.5 mg, 0.029 mmol). The resulting mixture was stirred at ambient temperature for 4 hours. The crude reaction mixture was diluted with 0.25 ml of DMSO, filtered, purified by prep LC and then lyapholized to yield 6.8 mg of the title compound, as a TFA salt.
