실험 절차
To a microwave vial, (E)-3-(4-((6-methoxy-2-(4-methoxyphenyl)benzo[b]thiophen-3-yl)oxy)phenyl)acrylamide (75 mg, 0.174 mmol) and Bu2SnO (4.33 mg, 0.02 mmol) were suspended in DME (3 mL). The vial was charged with TMSN3 (0.023 mL, 0.17 mmol) and the reaction was heated for 60 min at 180° C. under microwave irradiation. The reaction mixture was filtered to remove solids and concentrated onto silica gel. The crude material was purified by column chromatography (SiO2, 1-20% MeOH/DCM) to afford (E)-5-(4-((6-methoxy-2-(4-methoxyphenyl)benzo[b]thiophen-3-yl)oxy)styryl)-1H-tetrazole (66 mg, 0.15 mmol, 83% yield) as a white solid. 1H NMR (400 MHz, CD3OD) δ ppm=7.45-7.61 (m, 5 H), 7.32 (d, J=2.02 Hz, 1 H), 7.15 (d, J=9.09 Hz, 1 H), 6.98 (d, J=16.67 Hz, 1 H), 6.86-6.93 (m, 2 H), 6.78-6.86 (m, 3 H), 3.78 (s, 3 H), 3.69 (s, 3 H), LC/MS (m/z. MH+): 457.4.
