Procedure
To 1-(benzo[d][1,3]dioxol-5-yl)-N-(6-bromopyridin-3-yl)cyclopropanecarboxamide (72 mg, 0.2 mmol) in dioxane (0.400 mL), XANTPHOS (2.3 mg, 0.004 mmol), KtBuO (31 mg, 0.28 mmol), (DPPF)2PdCl2.CH2Cl2 (3.00 mg, 0.004 mmol), and 2-methoxyaniline (30 mg, 0.24 mmol), and Et3N (0.200 mL) were added. The reaction mixture was heated to 150° C. in a microwave reactor for 10 minutes. The resulting material was cooled to room temperature. The crude product was purified by column chromatography on silica gel to yield 1-(benzo[d][1,3]dioxol-5-yl)-N-(6-(2-methoxyphenylamino)pyridin-3-yl)cyclopropanecarboxamide which was then treated with HCl in MeOH to form the HCl salt (2.3 mg, 0.0053 mmol, 2.7%). ESI-MS m/z calc. 403.2, found; 404.5 (M+1)+Retention time 2.29 minutes.
