Reaction Steps

2-[2-fluoro-4-(methylsulfonyl)phenyl]-5-(4,4,5,5-tetramethyl-1,3,2-dioxa borolan-2-yl)-1H-benzo[d]imidazole (880 mg, 2.12 mmol), tert-butyl 4-(trifluoromethylsulfonyloxy)-5,6-dihydropyridine-1(2H)-carboxylate (700 mg, 2.12 mmol) and sodium carbonate (1.13 g, 11.48 mmol) were dissolved in DMF (20 ml) under N2 atmosphere. This mixture was degassed with nitrogen for 30 mins and added Pd(dppf)2Cl2.CH2Cl2 (138 mg, 0.17 mmol). This mixture stirred at 80° C. for 90 mins in microwave. Reaction mixture diluted with water and work up (AcOEt/H2O) afforded the crude. Crude was purified by combiflash using a mixture of AcOEt and Petether (35:65) to afford the titled compound (240 mg) as an off-white solid. 1H-NMR (δ ppm, DMSO-d6, 400 MHz): 12.80 (s, 1H), 8.49 (t, J 7.5, 1H), 8.02 (d, J 10.4, 1H), 7.92 (d, J 8.2, 1H), 7.88-7.67 (m, 1H), 7.66-7.54 (m, 1H), 7.48-7.39 (m, 1H), 6.18 (bs, 1H), 4.02 (bs, 2H), 3.57 (bs, 2H), 3.34 (s, 3H), 2.60-2.55 (m, 2H), 1.43 (s, 9H).
