실험 절차

A solution of 6 (4.38 g, 10 mmol) in 2 M NaOH (40 mL) was refluxed for 10 min and successively diluted with H2O (40 mL). The solution was acidified with glacial acetic acid. Standing in a refrigerator for 12 h, a solid crystallized, and was filtered and recrystallized from absolute ethanol to give 7 (2.3 g, 80%) as a white solid; mp 264-265° C. 1H NMR: δ 4.15-4.30 and 4.55-4.72 (2m, 2H, CH2N), 4.85-5.00 (m, 1H, CHO), 5.66 (br s, 1H, OH, disappears with D2O), 7.20-7.51 (m, 5H Ar), 8.02 (s, 1H, H-3), 12.20 (s, 1H, NH, disappears with D2O), 13.40 (s, 1H, NH, disappears with D2O). IR cm−1: 3362 (NH), 3142-2773 (OH), 1681 (CO). Anal. (C13H12N4O2S) C, H, N, S.
