Reaction Steps
A mixture of (E)-ethyl 3-(4-((E)-2-(4-hydroxyphenyl)-1-(1-(tetrahydro-2H-pyran-2-yl)-1H-indazol-5-yl)but-1-en-1-yl)phenyl)acrylate (222 mg, 0.42 mmol), 2-methoxyethanol (0.1 mL, 1.26 mmol), diisopropyl azidocarboxylate (0.24 mL, 1.26 mmol), and triphenylphosphine (330 mg, 1.26 mmol) in THF (5 mL) was stirred at room temperature overnight. The reaction mixture was absorbed on silica gel and purified by flash chromatography on silica gel eluting with 0 to 50% ethyl acetate/hexanes to afford 139 mg of the title compound as a yellow solid. 1H NMR (400 MHz, DMSO-d6): δ 8.11 (s, 1H), 7.72 (d, 1H), 7.62 (s, 1H), 7.48 (d, 1H), 7.40 (d, 2H), 7.21 (d, 1H), 7.08 (d, 2H), 6.88 (d, 2H), 6.79 (d, 2H), 6.47 (d, 1H), 5.85 (dd, 1H), 4.13 (qt, 2H), 4.02 (m, 2H), 3.90 (m, 1H), 3.74 (m, 1H), 3.62 (m, 2H), 3.29 (s, 3H), 2.47-2.37 (m, 3H), 2.01 (m, 2H), 1.76 (m, 1H), 1.59 (m, 2H), 1.22 (t, 3H), 0.89 (t, 3H).
