Procedure

To (E)-ethyl 3-(4-(4-(N-(2-(2-(2-(2-azidoethoxy)ethoxy)ethoxy)ethyl)sulfamoyl)phenoxy)-3,5-difluorophenyl)-2-methylacrylate (250 mg, 0.42 mmol) was added 4.4 M guanidine in methanol (as prepared in example 45) (1.0 mL, 4.4 mmol) and the reaction was stirred at RT. After 30 minutes, water (10 mL) was added, and the mixture was extracted with DCM (4×25 mL). The aqueous phase was adjusted to pH 7, and extracted with DCM (2×25 mL). The combined organic extracts were dried (Na2SO4) and concentrated to give the title compound (245 mg).
