실험 절차

N-(4-Cyanomethoxynaphthalen-1-yl)-3-fluoro-5-(4-methylpiperidin-1-yl)-benzamide (54 mg, 129 mmol), trimethylsilylazide (0.1 ml, 760 mmol) and dibutyltin oxide (5 mg) are heated to reflux in anhydrous toluene (3 ml) for 5 hours. After cooling to room temperature methanol (5 ml) is then added and the mixture stirred at room temperature for 30 min. The mixture is then evaporated to dryness and the residue recrystallized from ethyl acetate/hexanes to give 3-fluoro-5-(4-methylpiperidin-1-yl)-N-[4-(2H-tetrazol-5-ylmethoxy)-naphthalen-1-yl]-benzamide as a grey powder (22 mg). 1H NMR 300 MHz (DMSO-d6) 10.3 (s, 1H), 8.32 (dd, 1H, J=8.7 and 2.7 Hz), 7.87 (d, 1H, J=9.3 Hz), 7.54-7.62 (m, 2H), 7.42-7.5 (m, 2H), 7.17 (dd, 1H, J=15.9 and 9.3 Hz), 6.97 (d, 1H, J=13.2 Hz), 5.7 (s, 2H), 3.85 (d, 2H, J=19.8 Hz), 2.77 (m, 2H), 1.5-1.78 (m, 3H), 1.25 (m, 2H), 0.95 (d, 3H, J=6.6 Hz).
