実験手順

N-{1-[4-(1-Cyano-1-methylethyl)phenyl]ethyl}-2-(6,7-difluoro-1H-benzimidazol-1-yl)acetamide is synthesized according to example 1 by mixing (6,7-difluoro-1H-benzimidazol-1-yl)acetic acid (500 mg, 2.36 mmol) prepared according to scheme 2, 2-[4-(1-aminoethyl)phenyl]-2-methylpropanenitrile hydrochloride (525 mg, 2.36 mmol) prepared according to scheme 6, DMAP (570 mg, 4.71 mmol) and HATU (896 mg, 2.36 mmol) in DMF (10.0 mL). The product is purified on HPLCMS: Waters prep LCMS, 27 ml/min, Column: SynerSi (4μ) Polar RP, 21.2×50 mm, Mobile phase: A=water (0.05% TFA) B=MeCN, Gradient used 40% to 60% B in A, in 10 min. The fractions are combined, NaOH 1 N is added and the desired compound is extracted with ethyl acetate. The combined organic fractions are concentrated under reduced pressure to yield the product (450 mg, 2.36 mmol, 50%). 1H NMR (400 MHz, METHANOL-D4) δ ppm 1.49 (d, J=7.03 Hz, 3H) 1.68 (s, 6H) 5.03 (m, 1H) 5.20 (m, 2H) 7.30 (dt, J=11.23, 8.98, 7.32 Hz, 1H) 7.35-7.42 (m, 2H) 7.44-7.54 (m, 3H) 8.56 (s, 1H) MS [M+H], calcd: 383.2. found: 383.3.
