실험 절차

Acid compound 33 (0.7 g, 1.58 mmol) was dissolved in DCM (20 mL) and stirred at room temp under an atmosphere of argon. Triethylamine (0.26 mL, 1.9 mmol) and BOP reagent (0.77 g, 1.74 mmol) were added and the reaction mixture was stirred for 15 min. Dimethylamine (2.0 M solution in THF, 4.0 mL, 7.9 mmol) was added and the resulting solution was stirred at room temp for about 2-3 h. The solvent was removed under reduced pressure and the resulting oil was taken up in EtOAc (200 mL). The organic layer was extracted with 0.5 N NaOH (1×30 mL), water (2×100 mL) and brine (1×100 mL). Drying and concentration of the organic layer gave the desired amide 40 (0.7 g, 94.5%). 1H NMR (400 MHz, DMSO-d6): 7.33 (d, J=8.4 Hz, 2H), 7.26 (d, J=8.4 Hz, 2H), 7.11 (d, J=8.0 Hz, 1H), 6.93 (overlapped d, J=8.4 Hz, 2H), 6.92 (overlapped d, J=8.4 Hz, 2H), 5.50 (d, J=7.6 Hz, 2H), 2.93 (s, 3H), 2.90 (s, 3H), 2.84 (s, 3H), 2.82 (s, 3H), 2.79 (t, J=8.0 Hz, 2H), 2.59 (t, J=8.0 Hz, 2H), 1.37 (s, 9H).
