Reaction Steps

Lead tetra acetate (0.684 g, 0.0015 mol) was added to a solution of N-(4-chloropyridin-2-yl)-5-cyclopropylnicotinimidamide (42-1; 0.280 g, 0.001 mol) in toluene (30 mL) in a 40 mL microwave vial at RT. The reaction mixture was heated to 150° C. for 2 h under microwave irradiation. It was cooled to RT then diluted with water (50 mL) and extracted with ethyl acetate (2×50 mL). The combined organic layer was dried over sodium sulphate and concentrated under vacuum to afford the crude product, which was purified by silica gel column chromatography to afford the title compound. 1H NMR (400 MHz, DMSO) δ 9.08-9.02 (t, J=7.2 Hz, 2H), 8.52 (s, 1H), 8.10-8.05 (d, J=18.4 Hz, 2H), 7.32-7.31 (d, J=6.8 Hz, 1H), 2.08 (s, 1H), 1.07-1.05 (d, J=10.4 Hz, 2H), 0.82-0.81 (d, J=4.4 Hz, 2H). MS (M+1): 271.7.
