YieldReaction ConditionsOperation in experiment
52% With potassium phosphate; tetrakis(triphenylphosphine) palladium(0); In water; N,N-dimethyl-formamide; at 90℃; for 6h;Inert atmosphere; Step 1 : To a solution of 6-bromo-3-iodoimidazo[l,2-a]pyridine (21 g, 65.4 mmol), 4- Chlorophenylboronic acid (11.22 g, 71.9 mmol), K3P04 (27.7g, 130.8 mmol) in a mixture of DMF (100 mL) and water (15 mL), was added Pd(PPh3)4 (3.77 g, 3.27 mmol). The reaction mixture was heated at 90 C for 6 h under argon atmosphere prior to the addition of water (200 mL). The precipitate was isolated by filtration and was purified by column chromatography (silica gel, eluent CHCl3/MeOH 95:5) to afford of 6-bromo-3-(4- chlorophenyl)imidazo[l,2:a]pyridine (10.6 g, 52%) as a yellowish green solid. NMR (400 MHz, CDC13) delta 8.38 (s, 1H), 7.69 (s, 1H), 7.60 (d, J= 8.0 Hz, 2H), 7.82 (t, J= 9.2 - Hz, 1H), 7.58 (q, J= 5.2 Hz, 4H), MS (ESI) m/z 309 [C13H8BrN2Cl + 2H]+.
