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-4-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 40 mg (44%) of a clear oil. ESI-MS m/z calc. 453.4. found 454.3 (M+1)+. Retention times: 2.06 minutes. H NMR (400 MHz, DMSO) 8.85 (s, 1H), 8.20 (d, J=5.2 Hz, 1H), 7.86 (s, 1H), 7.54 (d, J=1.5 Hz, 1H), 7.39 (d, J=8.3 Hz, 1H), 7.32 (dd, J=1.6, 8.3 Hz, 1H), 6.97 (dd, J=1.2, 5.2 Hz, 1H), 6.77 (s, 1H), 3.87 (s, 3H), 2.31 (s, 3H), 2.09 (s, 3H), 1.51-1.48 (m, 2H), 1.17-1.15 (m, 2H).
