실험 절차

1-(4-Nitrophenyl)-5-tetrazolone (Example 8) (153 mg, 0.74 mmol), 2-hydroxyethyl phenyl sulfide (0.1 mL, 0.74 mmol), and triphenylphosphine (194 mg, 0.74 mmol) were suspended in tetrahydrofuran (2.5 mL). Diethyl azodicarboxylate (0.12 mL, 0.74 mmol) was added dropwise. After 12 hours the mixture was concentrated in vacuo to an oil. Silica gel chromatography (9:1 hexane/ethyl acetate) afforded a solid (230 mg, 90%). 1H NMR (CDCl3, 300 MHz) δ 8.30 (d, 9.2 Hz, 2 H), 8.13 (d, 9.2 Hz, 2 H), 7.37 (d, 7.0 Hz, 2 H), 7.20 (d, 7.0 Hz, 2 H), 7.12 (m, 1 H), 4.19 (t, 6.6 Hz, 2 H), 3.32 (t, 6.6 Hz, 2 H); MS (CI) m/z 344 (MH+).
