Procedure

1-(Pyridin-3-yl)cyclopropanecarboxylic acid (30.7 mg, 0.188 mmol), (R)-(1-(5,6-diaminopyridin-2-yl)piperidin-3-yl)(pyrrolidin-1-yl)methanone dihydrochloride (Intermediate 1) (75 mg, 0.19 mmol), and N-methylmorpholine (83 μL, 0.76 mmol) were combined and dissolved in N,N-dimethylformamide (1.0 mL). Benzotriazole-1-yl-oxy-tris-(dimethylamino)-phosphonium hexafluorophosphate (BOP) (122 mg, 0.207 mmol) was added and the reaction mixture was stirred at 50° C. for 18 h. The solvent was removed under reduced pressure and the residue was dissolved in dichloromethane. A saturated aqueous solution of sodium bicarbonate was added. The organics were collected and the aqueous layer was extracted with dichloromethane. The combined organics were washed with brine, dried over sodium sulfate, filtered and concentrated under reduced pressure. The residue was purified via flash chromatography (0-10% methanol in dichloromethane) to afford (R)—N-(2-amino-6-(3-(pyrrolidine-1-carbonyl)piperidin-1-yl)pyridin-3-yl)-1-(pyridin-3-yl)cyclopropanecarboxamide (69 mg, 84%). MS (AP+) (M+H) 435.2; LCMS retention time 1.51 min (Method L).
