The title compound was prepared according to the general amide coupling procedure by reacting acid 22 with amine 6 in DMF overnight. The crude product was purified with chromatography using CH2Cl2/MeOH (13/1) as eluent to give 260 mg white foaming, in 72% yield. 1H NMR (400 MHz, CDCl3): δ8.96 (s, 1H), 7.57 (d, J=8.48 Hz, 2H), 7.35-7.27 (m, 5H), 7.24 (d, J=8.48 Hz, 2H), 6.75 (m, 1H), 6.70 (m, 1H), 5.12-5.08 (m, 3H), 4.91 (m, 1H), 4.29 (m, 1H), 4.14 (s, 2H), 4.09 (s, 2H), 3.40 (m, 1H), 3.37 (m, 1H), 3.30 (q, J=6.68 Hz, 2H), 3.15 (q, J=6.71 Hz, 2H), 2.99 (m, 1H), 2.48 (s, 3H), 2.43 (t, J=6.48 Hz, 2H), 2.30-2.04 (m, 6H), 2.01-1.71 (m, 8H), 1.70-1.46 (m, 9H), 1.376 (d, J=6.80 Hz, 3H), 1.373 (d, J=6.84 Hz, 3H), 1.35-1.31 (m, 6H); 13C NMR (100 MHz, CDCl3): δ 173.50, 168.64, 167.15, 159.17, 156.55, 150.59, 138.31, 136.66, 136.51, 128.54, 128.12, 128.00, 127.12, 120.51, 77.24, 71.66, 71.50, 66.60, 58.90, 58.30, 51.68, 47.77, 47.24, 42.83, 40.98, 39.14, 35.33, 34.59, 32.82 (J 13C-19F 25.7 Hz), 29.82, 29.36, 28.71, 26.75 (J 13C-19F 10 Hz), 26.48, 25.87, 21.65, 13.15. mp 65-67° C.
