Procedure

2-(2-(3-azidopropyl)-5-(2,5-difluorophenyl)-2-phenyl-1,3,4-thiadiazol-3(2H)-yl)-5-bromo-1,3,4-thiadiazole (0.006 g, 0.011 mol) was dissolved in 0.25 mL THF, followed by addition of water (0.015 g, 15 μL) and triphenylphosphine (0.015 g, 0.057 mmol), and the reaction mixture was stirred at 23° C. overnight. The crude mixture was purified by directly loading onto a preparative TLC plate and eluting first with 12:1 (DCM:MeOH), followed by a second elution with 10:1 (DCM:MeOH) (both with NH4OH present), to afford the desired product (0.003 g, 53%). MS ESI (+) m/z 495/497 (M+1) detected; 1H NMR (400 MHz, CDCl3) δ 7.52 (m, 3H), 7.35 (t, 2H, J=7.6 Hz), 7.30 (d, 1H, J=7.2 Hz), 7.12 (m, 2H), 3.46 (m, 1H), 2.65 (m, 6H), 2.05 (m, 1H), 1.61 (m, 1H).
