Triphenylphosphine → tert-butyl {3-[3-(2,3-difluorophenyl)-2,2-dioxido-2,1,3-benzothiadiazol-1(3H)-yl]-1-phenylpropyl}methylcarbamate

Participants

Reaction Steps

In an analogous manner to general procedure II, 1-(2,3-difluorophenyl)-1,3-dihydro-2,1,3-benzothiadiazole 2,2-dioxide (prepared in an analogous manner as described in general procedure I, 115 mg, 0.41 mmol) was treated with triphenylphosphine (0.13 g, 0.49 mmol), tert-butyl (3-hydroxy-1-phenylpropyl)methylcarbamate (0.12 g, 0.45 mmol), and diisopropylazodicarboxylate (0.095 mL, 0.49 mmol) to provide 0.12 g tert-butyl {3-[3-(2,3-difluorophenyl)-2,2-dioxido-2,1,3-benzothiadiazol-1(3H)-yl]-1-phenylpropyl}methylcarbamate.
