Procedure

2-(7-cyano-1H-benzimidazol-1-yl)-N-[4-(1-cyano-1-methylethyl)-3-fluorobenzyl]acetamide is synthesized according to example 14 with (7-cyano-1H-benzimidazol-1-yl)acetic acid (150 mg, 0.746 mmol) prepared according to scheme 3, 2-[4-(aminomethyl)-2-fluorophenyl]-2-methylpropanenitrile hydrochloride (205 mg, 0.896 mmol) prepared according to scheme 8, Et3N (250 μL, 1.79 mmol) and HATU (341 mg, 0.896 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=21 mg as TFA salt, 0.043 mmol, 6%); 1H NMR (400 MHz, DMSO-D6) δ ppm 1.62-1.71 (m, 6H), 4.32 (d, J=5.86 Hz, 2H), 5.26 (s, 2H), 7.13-7.25 (m, 2H), 7.29-7.41 (m, 2H), 7.71 (d, J=7.42 Hz, 1H), 8.00 (d, J=8.01 Hz, 1H), 8.36 (s, 1H), 8.84-8.93 (m, 1H). MS [M+H], calcd: 376.2. found: 376.0.
