실험 절차

To a solution of 5-(4-Bromo-2-fluorophenylamino)-imidazo[1,5-a]pyridine-6-carboxylic acid (2.0 g, 5.7 mmol) and O-(2-vinyloxyethyl)-hydroxylamine (0.71 g, 6.8 mmol) in DMF (44 mL) was added EDCI hydrochloride (1.42 g, 7.41 mmol), HOBt (1.0 g, 7.41 mmol) and DIPEA (0.97 mL, 5.69 mmol). The reaction mixture was stirred at room temperature for 3 hours before being concentrated in vacuo. The resultant residue was dissolved in 1:1 diethylether:ethyl acetate (30 mL) and aqueous saturated sodium hydrogen carbonate solution (30 mL) was added. The resultant mixture was sonicated until a precipitate formed. The precipitate was collected by filtration and washed with 1:1 diethylether:ethyl acetate to yield the title compound as a tan solid (1.33 g, 53%). LCMS (Method B): RT=2.78 min, M+H+=435/437.
