실험 절차
3-Chloro-1-[2-(methylthio)ethyl]-4-phenyl-1H-pyrrole-2,5-dione (0.40 mmol, 113 mg) and 4-methoxyaniline (0.88 mmol, 109 mg) were dissolved in DMF (1 mL). The mixture was heated in a microwave reactor at 150° C. for 10 min. After cooling, the solvent was evaporated under reduced pressure. The residue was partitioned between water and CH2Cl2. The organic phase was evaporated and purified by flash chromatography using a pre-packed silica column. The desired product was eluted with heptane/EtOAc 2:1. Yield 118 mg (80%).1H NMR (400MHz, CDCl3) δ 7.26 (bs, 1H), 7.15-7.06 (m, 3H), 7.01-6.96 (m, 2H), 6.63-6.52 (m, 4H), 3.83 (t, J=7.0 Hz, 2H), 3.69 (s, 3H), 2.79 (t, J=7.0 Hz, 2H), 2.18 (s, 3H).
