(R)-2-propyloctanoic acid (100 mg, 0.48 mmol) was dissolved in 1 mL DMF. HATU (201 mg, 0.53 mmol) and NMM (192 μL, 1.73 mmol) were added and the solution was stirred for 5 min. 1400-W (94 mg, 0.528 mmol) was added and the solution was stirred for 2 h at rt. The reaction was quenched with TFA (142 μL, 1.87 mmol) TFA and MeOH (1 mL) and purified by preparative HPLC (5% to 100%, ACN/water) to give the product (Example 6) as a white solid. 1H-NMR (500 MHz, DMSO-d6) δ 9.80 (s, 1H), 9.22 (s, 1H), 8.76 (s, 1H), 8.37 (t, 1H), 7.34-7.37 (m, 1H), 7.22-7.29 (m, 3H), 4.47 (d, 2H), 4.42 (d, 2H), 2.18-2.24 (m, 4H), 1.46-1.50 (m, 2H), 1.20-1.31 (m, 12H), 0.84-0.87 (m, 6H). MS (ESI) 346 (M+H).
