Procedure

N-[4-(1-Cyano-1-methylethyl)-3-fluorobenzyl]-2-(6,7-difluoro-1H-benzimidazol-1-yl)acetamide is synthesized according to example 14 with (6,7-difluoro-1H-benzimidazol-1-yl)acetic acid (150 mg, 0.707 mmol) prepared according to scheme 2, 2-[4-(aminomethyl)-2-fluorophenyl]-2-methylpropanenitrile hydrochloride (194 mg, 0.848 mmol) prepared according to scheme 8, Et3N (237 μL, 1.70 mmol) and HATU (323 mg, 0.848 mmol) in DMF (3.0 mL). The product is purified by HPLC: Gilson prep pumps, Flow rate: 30 ml/min, Column: Gemini (50 21.2×50 mm, Mobile phase: A=water (0.075% TFA) B=MeCN (0.075% TFA). Yield=25 mg as TFA salt, 0.05 mmol, 7%). 1H NMR (400 MHz, DMSO-D6) δ ppm 1.74-1.87 (m, 6H), 4.43 (d, J=5.66 Hz, 2H), 5.22 (s, 2H), 7.19-7.40 (m, 2H), 7.45-7.61 (m, 2H), 8.34 (s, 1H), 8.91-9.04 (m, 1H). MS [M+H], calcd: 387.1. found: 387.0.
