Procedure

A mixture containing 3-{5-amino-6-[(methylamino)carbonyl]pyrazin-2-yl}-5-[(methyloxy)carbonyl]benzoic acid (0.34 g, 1.0 mmol), O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluroniumhexafluorophosphate (0.51 g, 1.6 mmol), (S)-(+)-1-aminoindan (0.17 g, 1.3 mmol), diisopropylethylamine (0.6 mL, 3.4 mmol) and DMF (70 mL) were stirred at room temperature for 12 h. The reaction mixture was diluted with water and extracted 3' with ethyl acetate and 3× with 5% aqueous lithium chloride, and dried over sodium sulfate. Filtration, concentration, and purification by reverse phase HPLC gave the product as a yellow solid (0.41 g, 90% yield). 1H NMR (400 MHz, d6-DMSO): δ 9.09 (d, 1H), 8.91 (s, 1H), 8.83 (d, 1H), 8.75 (t, 1H), 8.70 (t, 1H), 8.45 (t, 1H), 7.73 (br, 2H), 7.28 (d, 2H), 7.24-7.17 (m, 2H), 5.64-5.58 (q, 1H), 3.91 (s, 3H), 3.04-3.00 (m, 1H), 3.00-2.87 (m, 1H), 2.83 (d, 3H), 2.53-2.51 (m, 1H), 2.06-1.96 (m, 1H). MS (EI) for C24H23N5O4: 446 (MH+).
