(Scheme C). The amine 117 was reacted with 5-(2-hydroxyethoxy)-1H-indole-2-carboxylic acid as described in Example 7. The reaction mixture was poured into ice-water and the precipitate was collected to give 28 (88%): mp (EtOAc) 231-234° C.; 1H NMR [(CD3)2SO] δ 11.72 (s, 1H), 9.28 (s, 1H), 8.87 (d, J=1.6 Hz, 1H), 8.44 (d, J=8.9 Hz, 1H), 7.97 (dd, J=8.9, 1.6 Hz, 1H), 7.63 (s, 1H), 7.42 (d, J=8.9 Hz, 1H), 7.22 (d, J=1.7 z, 1H), 7.17 (d, J=2.2 Hz, 1H), 6.97 (dd, J=8.9, 2.4 Hz, 1H), 5.00-4.93 (m, 1H), 4.188-4.81 (m, 1H), 4.74-4.70 (m, 1H), 4.69-4.60 (m, 1H), 4.19-4.12 (m, 2H), 4.05-3.98 (m, 2H), 3.79-3.71 (m, 2H), 2.94 (s, 1H), 2.79 (s, 1H), 1.95 (s, 1H); 13C NMR δ 160.6, 153.2, 147.0, 142.6, 142.5, 132.2, 131.9, 130.4, 129.7, 127.4, 125.6, 124.4, 121.3, 120.5, 116.5, 116.1, 113.2, 106.3, 103.1, 69.8, 59.6, 54.8, 47.6, 41.4.
