関与物質

反応手順

Tributyltin azide (156 μL, 0.57 mmol) was added to a suspension of 3,5-bis(benzyloxy)-N-(5-cyanopyridin-2-yl)benzamide (180 mg, 0.41 mmol) in toluene (3 mL). The mixture was heated at reflux for 16 hours. The suspension was cooled and partitioned between ethyl acetate and hydrochloric acid (1M). The organic layer was concentrated in vacuo and the residue was purified by MPLC on silica MPLC (eluting with 1% methanol/DCM to 15% methanol/DCM). The tetrazole was obtained as a colourless solid (113 mg, 57%). 1H NMR δ (d6-DMSO): 5.19 (4H, s); 6.88 (1H, s); 7.26-7.48 (12H, m); 8.40 (1H, d); 8.46 (1H, dd); 9.04 (1H, s); 11.13 (1H, br s); m/z (LCMS; ESI+) 479 (MH+).
