Reaction Steps
A solution of N-(6-chloro-4,5-dimethylpyridin-2-yl)-1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamide (38 mg, 0.1 mmol) in DME (1 mL) was added to a reaction tube containing 2-methoxypyridin-3-ylboronic acid (46 mg, 0.15 mmol) and Pd(PPh3)4 (6 mg, 0.005 mmol). Saturated Na2CO3 solution was added (100 μL) and the reaction was stirred at 80° C. overnight. The reaction was filtered, concentrated and purified by column chromatography (0-50% ethyl acetate in hexanes) to obtain 50 mg (55%) of a clear oil. ESI-MS m/z calc. 453.4. found 454.5 (M+1)+. Retention times: 1.9 minutes. H NMR (400 MHz, DMSO) 8.81 (s, 1H), 8.22 (dd, J=1.9, 5.0 Hz, 1H), 7.84 (s, 1H), 7.57-7.53 (m, 2H), 7.38-7.31 (m, 2H), 7.05 (dd, J=5.0, 7.2 Hz, 1H), 3.78 (s, 3H), 2.29 (s, 3H), 1.89 (s, 3H), 1.50-1.47 (m, 2H), 1.16-1.13 (m, 2H)
