Procedure

To a mixture of (E)-3-(4-(4-(N-(2-(2-(2-(2-azidoethoxy)ethoxy)ethoxy)ethyl)sulfamoyl)phenoxy)-3,5-difluorophenyl)-N-(diaminomethylene)-2-methylacrylamide (70 mg, 0.11 mmol) and propargyl alcohol (6.4 mg. 0.11 mmol) in t-butanol (0.22 mL) and water (0.22 mL) was added 1 M sodium ascorbate (11 μL, 0.011 mmol) and 0.3 M copper sulfate (3.6 μL, 0.0011 mmol) and the reaction was stirred at RT. After 14 hours, the product was purified by preparative HPLC to give the title compound (22 mg) as a TFA salt. 1H-NMR (400 mHz, CD3OD) δ 7.93 (s, 1H), 7.84 (m, 2H), 7.44 (s, 1H), 7.30 (m, 2H), 7.11 (m, 2H), 4.64 (d, j=0.6 Hz, 2H), 4.55 (t, j=5.0 Hz, 2H), 3.86 (t, j=5.0 Hz, 2H), 3.57 (m, 4H), 3.52-3.42 (m, 6H), 3.03 (t, j=5.4 Hz, 2H), 2.18 (d, j=1.3 Hz, 3H). MS (m/z): 668.14 (M+H).
