Reaction Steps

EDC (0.22 g, 1.14 mmole) was added to a solution of 2-biphenylcarboxylic acid (0.22 g, 1.14 mmole), 1-methyl-2-(methylaminomethyl)indole (0.20 g, 1.15 mmole), and HOBt.H2O (0.15 g, 1.11 mmole) in DMF (20 mL) at RT. The reaction was stirred overnight, then was concentrated in vacuo. The residue was diluted with 5% NaHCO3 and extracted with CH2Cl2. The combined organic extracts were washed with brine and dried over MgSO4. Flash chromatography on silica gel (3% MeOH/CH2Cl2) followed by preparative TLC (3% MeOH/CH2Cl2) gave the title compound (0.10 g, 25%) as a light yellow solid: 1H NMR (360 MHz, CDCl3) indicated an approximately 5:1 mixture of amide rotamers; for the major rotamer: δ 7.03-7.58 (m, 13H), 6.19 (s, 1H), 4.50 -5.00 (m, 2H), 3.57 (s, 3H), 2.40 (s, 3H); for the minor rotamer: δ 7.03-7.58 (m, 13H), 6.14 (s, 1H), 4.50-5.00 (m, 2H), 3.38 (s, 3H), 2.76 (s, 3H); MS (ES) m/e 356 (M+H)+. Anal. Calcd for C24H22N2O.0.80H2O: C, 78.15; H, 6.45; N, 7.59. Found: C, 77.96; H, 6.29; N, 7.35.
