Procedure

To a solution of 2-isopropyl-1H-benzoimidazole-4-carboxylic acid (1-piperidin-4-ylmethylpiperidin-4-ylmethyl)amide (0.22 g, 0.55 mmol) and N,N-diisopropylethylamine (0.19 mL) in dichloromethane (5.0 mL) was added phenyl chloroformate (70 μL). The mixture was stirred at room temperature for 10 min, then concentrated in vacuo and purified via preparative reverse phase HPLC to afford the bis trifluoroacetate salt of the title compound as a white solid (98.4 mg, 0.13 mmol, 24%). (m/z): [M+H]+ calcd for C30H39N5O3 518.32; found 518.6. 1H NMR (300 MHz, MeOD-d3): δ (ppm) 1.14-1.28 (m, 2H), 1.39-1.53 (m, 6H), 1.52-1.62 (m, 2H), 1.70-1.78 (m, 2H), 1.92-2.06 (m, 4H), 2.82-2.97 (m, 6H), 3.32-3.38 (m, 2H), 3.43-3.50 (m, 1H), 3.52-3.69 (m, 2H), 4.04-4.12 (m, 1H), 4.18-4.26 (m, 1H), 6.91-6.98 (m, 1H), 7.08-7.13 (m, 1H), 7.21-7.28 (m, 1H), 7.45-7.50 (m, 1H), 7.73-7.77 (m, 1H), 7.81-7.87 (m, 1H), 9.02-9.32 (brs, 1H).
