実験手順

To a solution of (S)-2-(5-fluoro-2-(5-fluoro-1-tosyl-1H-pyrrolo[2,3-b]pyridin-3-yl)pyridin-4-ylamino)-3,3-dimethylbutyl methanesulfonate, 55a, (10.5 g, 18.11 mmol) in dry DMF (200 mL) was added potassium thioacetate (3.1 g, 27.1 mmol). The brown solution was heated with stirring at 80° C. for 1 hour. The thick brown suspension was poured into water and extracted with EtOAc (3×100 mL). The combined organic phases were dried (MgSO4), filtered and concentrated under reduced pressure. The crude residue was purified by silica gel chromatography (0-30% EtOAc/Hexanes gradient) to afford 6.8 g of the desired product, 56a, as a pale brown solid: 1H NMR (400 MHz, CDCl3) δ 8.41 (m, 2H), 8.23 (s, 1H), 8.01 (m, 3H), 7.23-7.16 (m, 2H), 4.99 (d, J=10.1 Hz, 1H), 4.37 (m, 1H), 3.21 (dd, J=13.8, 2.3 Hz, 1H), 3.09-2.95 (m, 1H), 2.31 (s, 3H), 2.16 (s, 3H), 1.02 (s, 9H); LC/MS (10-90% ACN/water 5 min with 0.9% FA) m/z 560.99 (M+H) RT=4.14 minutes.
