Procedure

To a solution of 1-(pyrazin-2-yl)cyclopropanecarboxylic acid (0.11 g, 0.669 mmol) in anhydrous dichloromethane (15 mL) was added O-(7-azabenzotriazol-1-yl)-N,N,N′,N′,-tetramethyluronium hexafluorophosphate (HATU) (0.3 g, 0.803 mmol) and diisopropylethylamine (0.35 mL, 2 mmol) at room temperature. The mixture was stirred for 10 min and then (R)-(1-(5,6-diaminopyridin-2-yl)piperidin-3-yl)(pyrrolidin-1-yl)methanone dihydrochloride (0.29 g, 0.803 mmol) was added. The reaction mixture was stirred for 30 min. The solvent was removed under reduced pressure and the residue was partitioned between ethyl acetate and water. The organic layer was dried over sodium sulfate, filtered and concentrated under reduced pressure. The crude material was purified via column chromatography (100-200 mesh silica gel, 0-5% methanol in dichloromethane) to afford (R)—N-(2-amino-6-(3-(pyrrolidine-1-carbonyl)piperidin-1-yl)pyridin-3-yl)-1-(pyrazin-2-yl)cyclopropanecarboxamide (100 mg). MS (ES+APCI) (M+H) 436.1.
