Versuchsvorschrift
N-(3-cyanothiophen-2-yl)-2-(4-methoxyphenyl)acetamide (285 mg, 1.05 mmol), and azidotributylstannane (614 mg, 1.85 mmol) in toluene (10 ml) was placed into a preheated oil bath at 100° C. After stirring for 6 h, The solution was concentrated and directly purified by HPLC to yield N-(3-(2H-tetrazol-5-yl)thiophen-2-yl)-2-(4-methoxyphenyl)acetamide. Method [7] Retention time 4.92 min by HPLC (MH+ 316). 1H NMR (300 MHz, DMSO) δ 11.05 (s, 1H), 7.37 (d, J=6.0 Hz, 1H), 7.30 (d, J=8.4 Hz, 2H), 7.23 (d, J=6.0 Hz, 1H), 6.94 (d, J=8.4 Hz, 2H), 3.88 (s, 2H), 3.76 (s, 3H).
