実験手順

To a solution of 5-(4-cyclopropyl-2-fluoro-phenylamino)-imidazo[1,5-a]pyridine-6-carboxylic acid (2-vinyloxy-ethoxy)-amide (270 mg, 0.681 mmol) in methanol (10 mL) was added 1M hydrochloric acid (2 mL, 2 mmol.) and the mixture stirred at room temperature for 2 hours. Solvent was removed in vacuo, and then saturated aqueous NaHCO3 added and the mixture extracted with ethyl acetate. The organic layer was separated, dried (Na2SO4), filtered and concentrated in vacuo. The resultant residue was triturated with TBME and the solid collected by filtration to give the title compound as an off-white solid (103 mg, 41%). LCMS (Method A): RT5.68 [M+H] 371. 1HNMR (DMSO-d6, 400 MHz) 7.81 (1H, s), 7.37-7.34 (1H, m), 7.27 (1H, d, J=9.37 Hz), 6.95 (1H, d, J=9.34 Hz), 6.91 (1H, dd, J=12.49, 1.92 Hz), 6.75 (1H, dd, J=8.27, 1.96 Hz), 6.56-6.46 (1H, m), 3.71-3.65 (2H, m), 3.48-3.43 (2H, m), 1.89-1.80 (1H, m), 0.91-0.85 (2H, m), 0.65-0.57 (2H, m).
