Procedure

The amide is synthesized according to example 1 by mixing (7-chloro-1H-benzimidazol-1-yl)acetic acid (521 mg, 2.48 mmol) prepared according to scheme 1, 2-[4-(1-Aminoethyl)-2-fluorophenyl]-2-methylpropanenitrile hydrochloride 721 mg, 2.97 mmol) prepared according to scheme 7, Et3N (824 μL, 5.95 mmol) and HATU (1.13 g, 2.97 mmol) in DMF (10.0 mL). The product is purified by HPLC: Gilson prep pumps, Flow rate: 30 ml/min, Column: Gemini (5 u) 21.2×50 mm, Mobile phase: A=water (0.075% TFA) B=MeCN (0.075% TFA), (421 mg as TFA salt, 0.82 mmol, 33%); 1H NMR (400 MHz, DMSO-D6) δ ppm 1.38 (d, J=7.03 Hz, 3H), 1.64-1.76 (m, 6H), 4.88-4.98 (m, 1H), 5.27 (s, 2H), 7.18-7.28 (m, 3H), 7.28-7.33 (m, 1H), 7.41 (t, J=8.30 Hz, 1H), 7.65 (d, J=7.81 Hz, 1H), 8.47 (s, 1H), 8.85 (d, J=7.62 Hz, 1H). MS [M+H], calcd: 399.9, found: 399.3.
