Versuchsvorschrift

To a suspension of 5-(2-fluoro-4-iodophenylamino)-imidazo[1,5-a]pyridine-6-carboxylic acid (2-vinyloxyethoxy)-amide (2.87 g, 5.95 mmol) in methanol (45 mL) was added aqueous hydrochloric acid (11.9 mL, 1M, 11.9 mmol). The reaction mixture was stirred at room temperature for 45 minutes during which time the solids dissolved. The reaction mixture was concentrated in vacuo to remove the methanol. The resultant solution was diluted with 1:1 tert-butylmethylether: ethyl acetate (20 mL) and aqueous saturated sodium hydrogen carbonate solution (20 mL) added. The resultant mixture was sonicated until a precipitate formed and the precipitate was collected by filtration and dried in vacuo at 45° C. to yield the title compound as a yellow solid (2.5 g, 92%). LCMS (Method A): RT=5.58 min, M+H+=457. 1H NMR (DMSO-d6, 400 MHz) 8.05 (1H, s), 7.58 (1H, dd, J=10.69, 1.92 Hz), 7.43 (1H, s), 7.39 (1H, d, J=9.33 Hz), 7.31-7.28 (1H, m), 6.89 (1H, d, J=9.31 Hz), 6.34 (1H, t, J=8.68 Hz), 4.64 (1H, s), 3.64 (2H, t, J=4.78 Hz), 3.46 (2H, m).
