Versuchsvorschrift

To a solution of 2-(4-((5-(2-(4-chloro-3-methoxyphenyl)propan-2-yl)-1-(4-fluorophenyl)-1H-imidazol-2-ylthio)methyl)-3,5-difluorophenoxy)ethyl methanesulfonate (400 mg, 0.624 mmol) in DMF (6 mL) at 0° C. was added NaN3 (60 mg, 0.922 mmol). After stirring 1 h, the residue was partitioned in EtOAc (20 mL) and water (20 mL). The organic layer was washed with 1M HCl (10 mL) and water (10 mL) successively, dried over MgSO4, filtered and evaporated. The residue was purified by column chromatography (CH2Cl2/MeOH=20:1) to give 2-(4-(2-azidoethoxy)-2,6-difluorobenzylthio)-5-(2-(4-chloro-3-methoxyphenyl)propan-2-yl)-1-(4-fluorophenyl)-1H-imidazole (320 mg, 87% yield) as a white foam. 1H NMR (400 MHz, CDCl3) δ 7.22 (s, 1H), 7.16 (d, J=8.24 Hz, 1H), 6.77 (t, 2H), 6.55 (d, J=2.09 Hz, 1H), 6.51 (dd, J=8.25 Hz, 1H), 6.39-6.32 (m, 4H), 4.05 (m, 4H), 3.78 (s, 3H), 3.60 (t, 2H), 1.49 (s, 6H).
