YieldReaction ConditionsOperation in experiment
64% A mixture of 6-bromo-3-iodoimidazo[l,2-alpha]pyridine (3.0 g, 9.29 mmol), 1- ethoxyvinyltri-n-butyltin (3.3 mL, 9.75 mmol) and dichlorobis(triphenylphosphine)- palladium(II) (325 mg, 0.46 mmol) in 1,4-dioxane (90 mL) was heated to 100 0C in a sealed tube for 16 h. The reaction mixture was cooled to rt, diluted with ethyl acetate, filtered through a pad of silica gel (elute with ethyl acetate) and concentrated under reduced pressure. The residue was taken up in THF (50 mL) and treated with 6N HCl (3.1 mL, 18.6 mmol). After 1 h, the mixture was concentrated under reduced pressure, triturated with water and adjusted to pH ~12 with IN NaOH. The mixture was extracted 3 X with ethyl acetate and the combined extracts were dried (Na2SO4), filtered and concentrated under reduced pressure. The residue was purified by silica gel chromatography (97:3 EtOAc/MeOH) to give 1.41 g (64%) of l-(6-bromoimidazo[l,2-alpha]pyridin-3-yl)ethanone as a pale yellow solid. MS(ES)+ m/e 240.7 [M+H]+.
