Reaction Steps

To aniline 126 (0.58 g, 1.1 mmol) and DIPEA (0.58 mL, 0.43 g, 3.3 mmol) in dry DMF (20 mL) was added 1-(4-fluorophenylcarbamoyl)cyclopropanecarbpxylic acid (0.35 g, 1.5 mmol) and HATU (0.72 g, 1.9 mmol) and the mixture was stirred at r.t. for 18 h. It was then partitioned between ethyl acetate and water, the organic phase was washed with water, 1M NaOH, brine, dried (MgSO4), filtered, and concentrated. Silica gel chromatography (ethyl acetate) afforded title compound 146 (0.60 g, 74% yield). 1H NMR (400 MHz, DMSO-d6) δ (ppm): 10.40 (s, 1H), 10.01 (s, 1H), 8.52-8.49 (m, 2H), 8.33 (s, 1H), 8.27-8.24 (m, 1H), 7.92-7.88 (m, 1H), 7.78 (dd, J=8.2, 2.1 Hz, 1H) 7.65-7.60 (m, 2H), 7.52-7.42 (m, 2H), 7.14 (t, J=8.8 Hz, 2H), 6.65 (d, J=5.1 Hz 1H), 4.47 (s, 2H), 3.42-3.30 (m, 4H), 3.22 (s, 3H), 1.46-1.30 (m, 13H). MS (m/z): 730.1 (M+H).
