실험 절차

To a stirred suspension of Methyl 3-amino-4-iodobenzoate (1.67 g, 6 mmol) and Methacrylic acid (568 mg, 6.6 mmol) in dichloromethane (60 mL) and DMF (60 mL) were added O-(7-Azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (HATU) (2.5 g, 6.6 mmol) and then a solution of N,N-diisopropylethylamine (1.16 g, 1560 μL, 9 mmol) in DMF (20 mL). The reaction mixture was stirred at ambient temperature for 24 h. The reaction medium was acidified by adding a 1.2 M hydrochloric acid solution and extracted with ethyl acetate. The organic phase was washed with water, dried (MgSO4), and concentrated to give the amide which was purified by flash chromatography (AcOEt/heptane: 5/5).
