実験手順

A mixture of 2-(2,6-dimethylphenyl)-1H-indole-6-carboxylic acid. (17 mg, 60 μmol), 4-tert.-butylaniline (10 μL, 9.4 mg, 63 μmol) and HATU (33 mg, 87 μmol) in DMF (3 mL) was stirred, initially at ambient temperature, then at 60° C. for 18 h. The mixture was poured into ethyl acetate and extracted once with water and five times with brine. The organic layer was dried, filtered, and solvent was removed under reduced pressure. The residual material was chromatographed using a gradient of 20-60% heptane/ethyl acetate to give 2-(2,6-dimethylphenyl)-1H-indole-6-carboxylic acid (4-tert-butylphenyl)-amide. 1H NMR (CDCl3, 400 MHz) δ 8.54 (s, broad, 1H), 8.12 (s, 1H), 7.89 (s, 1H), 7.70 (d, J=8.3 Hz, 1H), 7.56 (m, 3H), 7.37 (d, J=8.7 Hz, 2H), 7.15 (d, J=7.6 Hz, 2H), 6.46 (s, 1H), 2.18 (s, 6H), 1.33 (s, 9H). MS (m/z) 397.2 (M+1).
