Procedure

To aniline 139 (Scheme 7) (0.46 g, 1.1 mmol) in dry DMF (20 mL) was added acid 1-(phenylcarbamoyl)cyclopropanecarbpxylic acid (0.46 g, 2.2 mmol), DIPEA (0.98 mL, 5.6 mmol) and HATU (1.07 g, 2.81 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 collected, washed with water, 1M NaOH, saturated NH4Cl, and brine, dried (MgSO4), filtered and concentrated. Silica gel chromatography of the residue (eluent 2% methanol/ethyl acetate) afforded 140 (0.23 g, 34% yield). 1H NMR (400 MHz, DMSO-d6) δ (ppm): 10.37 (s, 1H), 9.98 (s, 1H), 8.68 (s, 1H), 8.53 (d, J=5.3 Hz, 1H), 8.40 (s, 1H), 8.31 (d, J=8.2 Hz, 1H), 7.97 (dd, J=8.2, 2.0 Hz, 1H), 7.90 (dd, J=13.1, 2.0 Hz, 1H), 7.62 (d, J=7.6, 2H), 7.53-7.46 (m, 2H), 7.30 (t, J=7.4 Hz, 2H), 7.06 (t, J=7.4 Hz, 1H), 6.66 (d, J=5.3 Hz, 1H), 5.88 (s, 1H), 4.11-3.97 (m, 4H), 1.47 (br s, 4H). MS (m/z): 597.2 (M+H).
