Reaction Steps

(S)-1-(1-(2-methoxybenzyl)-1H-imidazol-2-yl)-2-phenylethanamine (75 mg, 0.2 mmol), 2-(5-hydroxy-1H-indol-3-yl)acetic acid (47 mg, 0.25 mmol) and HATU (97 mg, 0.26 mmol) were combined in DMF (2 mL) and treated with diisopropylethylamine (70 μL). The reaction was stirred for 30 min and the purified by RP HPLC to provide the title compound: 1H NMR (400 MHz, DMSO-d6) δ 10.53 (d, 1H), 8.67 (d, 1H), 7.58 (s, 1H), 7.38-7.28 (m, 2H), 7.20-7.12 (m, 3H), 7.12-6.98 (m, 4H), 6.91-6.79 (m, 3H), 6.72 (d, 1H), 6.57 (dd, 1H), 5.38-5.31 (m, 1H), 5.17 (d, 2H), 3.71 (s, 3H), 3.40-3.22 (m, 3H), 3.16 (dd, 1H). MS (m/z) 481.2 [M+H]+.
