Triethylamine → 1-(1,3-Dihydroisobenzofuran-5-yl)-N-(6'-methoxy-3,5'-dimethyl-2,3'-bipyridin-6-yl)cyclopropanecarboxamide

To a solution of 1-(1,3-dihydroisobenzofuran-5-yl)cyclopropanecarboxylic acid (40.8 mg, 0.2 mmol) in dichloromethane (2 mL) was added thionyl chloride (43.8 μL, 0.60 mmol) followed by DMF (1 drop) and the reaction was stirred at room temperature for 30 minutes and then the solvent was evaporated. Toluene (˜1 mL) was added and mixed with the residue and then removed by rotovap. The residue was then dissolved in dichloromethane (1 mL) and a solution of 6′-methoxy-3,5′-dimethyl-2,3′-bipyridin-6-amine (45.8 mg, 0.20 mmol) and Et3N (83.6 μL, 0.60 mmol) in dichloromethane (1 mL) was added. The reaction was stirred at room temperature for 12 hours. The reaction was then concentrated. The residue was dissolved in DMSO and purified by reverse phase HPLC (10-99% CH3CN in water) to yield 40 mg of the desired product. ESI-MS m/z calc. 415.2. found 416.5 (M+1)+. Retention time 1.87 minutes.
