Reaction Steps

To a solution of acid 69 (100 mg, 0.48 mmol), aniline (60 μL, 0.66 mmol), and DMAP (5 mg) in THF (5 mL) was added EDC (119 mg, 0.57 mmol). The reaction mixture was stirred overnight, then partitioned between H2O (10 mL) and EtOAc (15 mL). The layers were separated, and the aqueous portion extracted with EtOAc (3×10 mL). The organic fractions were combined, washed with sat. NH4Cl (5 mL), then brine, dried over MgSO4, and filtered. Concentration under reduced pressure gave 70 as a white crystalline solid (130 mg, 0.46 mmol, 95%). 1H-NMR (400 MHz, DMSO-d6) δ 9.84 (s, 1H), 7.57 (d, 2H), 7.26 (t, 2H), 7.00 (t, 1H), 6.92 (t, 1H), 2.91 (dt, 2H), 2.85 (s, 3H), 1.58 (m, 2H), 1.47 (m, 2H), 1.31 (m, 2H).
