실험 절차

To a mixture of 2-methoxypyrimidin-5-ylboronic acid (92 mg, 0.60 mmol) and N-(6-chloro-5-methylpyridin-2-yl)-1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)cyclopropane-carboxamide (180 mg, 0.50 mmol) in DME (3 mL) and 2 M Na2CO3 (1 mL) was added Pd(PPh3)4 (29 mg, 0.025 mmol). The mixture was heated in a microwave oven at 120° C. for 30 min. The mixture was partitioned between ethyl acetate and H2O and the aqueous layer was extracted with ethyl acetate (3×). The combined organic layers were washed with brine, dried over MgSO4, and concentrated under reduced pressure. The residue was purified by column chromatography to yield 1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)-N-(6-(2-methoxypyrimidin-5-yl)-5-methylpyridin-2-yl)cyclopropanecarboxamide (140 mg, 64%). 1H NMR (400 MHz, CDCl3) δ 8.56 (s, 2H), 8.03 (d, J=8.4 Hz, 1H), 7.58 (s, 1H), 7.53 (d, J=8.5 Hz, 1H), 7.18 (dd, J=8.6, 2.1 Hz, 1H), 7.13 (d, J=1.6 Hz, 1H), 7.04 (d, J=8.2 Hz, 1H), 3.98 (s, 3H), 2.26 (s, 3H), 1.68 (q, J=3.6 Hz, 2H), 1.12 (q, J=3.6 Hz, 2H). MS (ESI) m/e (M+H+) 441.3.
