Procedure

To a solution of 3-[[[3-(1,1,2,2-tetrafluoroethoxy)phenyl]methyl](3,3,3-trifluoro-2-hydroxypropyl)amino]benzonitrile (76 mg, 0.17 mmol) in 2 mL of toluene was added trimethyltin azide (41 mg, 0.20 mmol). The reaction mixture was heated to 105° C. and stirred overnight. TLC showed starting material to still be present so additional trimethyltin azide (41 mg, 0.20 mmol) was added. The reaction mixture was stirred overnight at 105° C., cooled to room temperature, then THF (800 μL) and concentrated HCl (500 μL) were added. HPLC analysis showed 2 peaks after 5 hours, so additional concentrated HCl (200 μL) was added. After stirring overnight, HPLC analysis showed the reaction to be complete. The mixture was filtered through a celite plug and evaporated in vacuo. The residue was purified by reverse phase HPLC eluting with 10% to 90% acetonitrile in water to give 27.2 mg (33%) of the desired tetrazole product as an oil. HRMS calcd. for C19H16F7N5O2: 480.1270 [M+H]+, found: 480.1252. 1H NMR (CDCl3) δ3.66-3.99 (m, 2H), 4.45-4.75 (m, 3H), 5.80 (dt, 1H), 6.49-6.70 (m, 1H), 6.95 (s, 1H), 6.97-7.06 (m, 3H), 7.18-7.28 (m, 3H), 7.34 (s, 1H).
