실험 절차

6-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)isobenzofuran-1(3H)-one (39 mg, 0.15 mmol), N-(6-chloro-5-methylpyridin-2-yl)-1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamide (37 mg, 0.10 mmol) and Pd(PPh3)4 (6 mg, 0.005 mmol) were placed in a microwave vial. DME (1 mL) and saturated aq. Na2CO3 (100 μL) were added and the reaction vial was flushed with N2 and sealed. The reaction was heated in the microwave at 120° C. for 20 minutes before it was partitioned between ethyl acetate and H2O. The organic layer was filtered and concentrated. The residue was dissolved in DMSO and purified by reverse-phase HPLC to yield 1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)-N-(5-methyl-6-(3-oxo-1,3-dihydroisobenzofuran-5-yl)pyridin-2-yl)cyclopropanecarboxamide. ESI-MS m/z calc. 464.1. found 465.3 (M+1)+. Retention time 1.96 minutes. 1H NMR (400 MHz, DMSO-d6) δ 8.99 (s, 1H), 7.94-7.86 (m, 3H), 7.76-7.73 (m, 2H), 7.56 (d, J=1.5 Hz, 1H), 7.41-7.33 (m, 2H), 5.47 (s, 2H), 2.26 (s, 3H), 1.53-1.50 (m, 2H), 1.19-1.16 (m, 2H).
