실험 절차

2-Aminodibenzthiophene (Bull. Soc. Chim. Fr. (1 996), 133 (6), 597-610; 500 mg, 2.5 mmol) was dissolved DMF (10 ml) and 2-(1,2,4-triazol-1-yl)acetic acid (318 mg, 2.5 mmol) was added in one portion followed by 1-hydroxybenztriazole hydrate (383 mg, 5.0 mmol) and EDAC (960 mg, 5.0 mmol). The resultant mixture was stirred for 16 hours at ambient temperature then poured on to water (100 ml). A fine white solid was collected which was washed extensively with water, methanol (25 ml) and ether (25 ml) to leave a colourless solid (650 mg). NMR: 10.62 (brs, 1H), 8.18 (m, 2H), 8.16 (m, 3H), 7.99 (m,3H), 7.62 (dd, 1H), 7.50 (m, 2H), 5.20 (s, 2H); m/z 309.
