실험 절차

Methyl 4-(4-(4-[(phenysulfonyl)amino]phenyl(1,3-thiazol-2-yl))-5-methiothiothiophene-2-carboxylate: Methyl 4-(4-(4-aminophenyl)(1,3-thiazol-2-yl))-5-methylthiothiophene-2-carboxylate (100 mg, 0.28 inmol) was dissolved in dry dichloromethane (10 mL). To this, N-methyl morpholine (46 μL, 0.42 mmol) and dimethylaminopyridine (3.4 mg, 0.028 mmol) were added, the mixture was cooled on an ice bath, and benzenesulfonyl chloride 35 μL, 0.28 mmol) was added dropwise. The mixture was then stirred for 24 h at room temperature. Workup was carried out as in Example 134, step (c). Trituration with dichloromethane and methanol gave methyl 4-(4-{4-[(phenylsulfonyl)amino]phenyl}(1,3-thiazol-2-yl))-5-methylthiothiophene-2-carboxylate (44 mg, 31%) as a crystalline solid. 1H-NMR (DMSO-d6; 300 MHz) δ 10.46 (s, 1H), 8.19 (s, 1H), 8.05 (s, 1H), 7.91 and 7.19 (AB quartet, 2H, J=8.7 Hz), 7.81 (m, 2H), 7.64-7.54 (m, 3H) 3.85 (s, 3H), 2.74 (s, 3H). Mass spectrum (MALDI-TOF, CHCA matrix, m/z): Calcd. for C22H18N2O4S4 504.2 (M+H), found 504.1
