Reaction Steps

To a solution of N-[4-(3-tert-butyl-5-{[({2-fluoro-4-[(2-methylpyridin-4-yl)oxy]-phenyl}amino)carbonyl]amino}-1H-pyrazol-1-yl)phenyl]-2-methoxyacetamide (500 mg, 0.97 mmol) in anhydrous THF (20 mL) was added borane-methyl sulfide complex (2.0 M solution in THF, 5 mL, 10 mmol), and the reaction was stirred at reflux for 7 h. The reaction mixture was cooled to room temperature, partitioned between EtOAc (50 mL) and water (50 mL), and the organic layer was washed with brine, dried over Na2SO4, and concentrated at reduced pressure. The residue was purified by MPLC (1:1 hexanes/EtOAc) to give 33 mg (7%) of the desired product. 1H-NMR (DMSO-d6) δ 8.65 (s, 1H), 8.42 (d, J=4.8 Hz, 2H), 8.34 (s, 1H), 7.58 (d, J=6.6 Hz, 2H), 7.21 (d, J=6.6 Hz, 2H), 7.06 (d, J=6.9 Hz, 2H), 6.84 (d, J=4.8 Hz, 2H), 6.73 (d, J=6.9 Hz, 2H), 6.43 (s, 1H), 5.23 (s, 1H), 3.57 (t, J=5.7 Hz, 2H), 3.35 to 3.30 (m, 5H), 1.32 (s, 9H); MS LC-MS [M+H]+=529, RT=2.20 min.
