실험 절차

To a solution of 5-(3-iodo-1H-indol-5-yl)-N-(4-methoxybenzyl)-1,3,4-oxadiazol-2-amine (0.5 g, 1.12 mmol) in DMF (5 mL) at −25° C. was added NaH (0.059 g, 50% in mineral oil, 1.23 mmol) portion wise. The mixture was stirred for 5 min at −25° C. then a solution of 4-methyl benzene sulfonyl chloride (0.235 g, 1.23 mmol) in DMF (1 mL) was added at same temperature dropwise. The reaction was stirred at −25° C. for 10 min. The mixture was poured into ice cold water and a white solid precipitated out which was collected by filtration and recrystallized by triturating it with 1:3 volume of EtOH (2 mL) and CHCl3 (6 mL) to give 5-(3-iodo-1-tosyl-1H-indol-5-yl)-N-(4-methoxybenzyl)-1,3,4-oxadiazol-2-amine (0.450 g, 0.75 mmol, 66.96%). MS (ESI, pos. ion) m/z: 601.1 (M+1); 1H-NMR (DMSO-d6) δ8.312 (s, 1H), 8.21 (s, 1H), 8.13 (s, 1H), 7.9-7.90 (m, 3H), 7.68 (s, 1H), 7.44 (d, J=9 Hz, 2H), 7.33 (d, J=9 Hz, 2H), 6.92 (d, J=9 Hz, 2H), 4.38 (d, J=6 Hz, 2H), 3.73 (s, 3H), 2.33 (s, 3H).
