실험 절차

2-[4-(1-Aminoethyl)phenyl]-2-methylpropanenitrile hydrochloride prepared according to scheme (557 mg, 2.49 mmol), (7-cyano-1H-benzimidazol-1-yl)acetic acid (500 mg, 2.49 mmol) prepared according to scheme 3 and DMAP (601 mg, 4.97 mmol) are mixed in DMF (10.0 mL). HATU (945 mg, 2.49 mmol) is added, and the mixture is stirred for 18 hours. The reaction mixture is filtered and then purified on HPLCMS: Waters prep LCMS, Flow rate: 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 70% B in A, in 10 min. The fractions are combined, NaOH 1N is added and the desired compound is extracted with ethyl acetate. The combined organic fractions are concentrated under reduced pressure to yield the product (610 mg, 1.64 mmol, 66%). 1H NMR (400 MHz, METHANOL-D4) δ ppm 1.50 (d, J=7.03 Hz, 3H) 1.68 (s, 6H) 4.98-5.09 (m, 1H) 5.33 (s, 2H) 7.37-7.43 (m, 3H) 7.46 (d, J=8.20 Hz, 2H) 7.68 (d, J=7.62 Hz, 1H) 7.97 (dd, J=8.20, 0.98 Hz, 1H) 8.28 (s, 1H) 8.89 (d, J=7.62 Hz, 1H), MS [M+H], calcd: 372.2. found: 372.3.
