“…1 H NMR (500 MHz, CDCl 3 ) δ 10.47 (s, 1H), 8.42 (d, J = 3.9 Hz, 1H), 7.95 (m, 3H), 7.41 (d, J = 8.7 Hz, 2H), 7.31 (m, 1H), 7.08 (d, J = 9.7 Hz, 1H), 6.92 (d, J = 8.7 Hz, 2H), 5.30 (s, 2H), 3.73 (s, 3H), 2.85 (m, 1H), 0.71 (m, 2H), 0.55 (m, 2H). 13 (13). To a solution of 29d (147 mg, 0.57 mmol), HATU (255 mg, 0.67 mmol), and DIPEA (0.270 mL, 1.545 mmol) in DMF (5 mL) was added 33 (100 mg, 0.515 mmol) and stirred for 16 h. The RM was added to ice-cold water, and the resulting solid was collected, washed with cold EtOAc, then cold 50% EtOAc in pet ether, and then pentane, and dried to give 13 (105 mg, 46%).…”
