실험 절차

2-[4-(1-Aminoethyl)phenyl]-2-ethylbutanenitrile (520 mg, 2.41 mmol) prepared according to scheme 24, (6,7-difluoro-1H-benzimidazol-1-yl)acetic acid (510 mg, 2.41 mmol) prepared according to scheme 2 and Et3N (731 mg, 7.22 mmol, 1.00 mL) are mixed in MeCN (15.0 mL). HATU (915 mg, 2.41 mmol) is added and the mixture is stirred for 2 hours. 1N NaOH (40.0 mL) is added, and the aqueous phase is extracted with EtOAc (4 times 40.0 mL). The combined organic phases are dried with MgSO4, filtered and concentrated on the rotovaporator. The product is purified by HPLC: Gilson prep pumps, Flow rate: 30 ml/min, Column: Gemini (5%) 21.2×50 mm, Mobile phase: A=water (10 mM NH4CO3) B=MeCN, (804 mg, 1.96 mmol, 81%). 1H NMR (400 MHz, DMSO-D6) δ ppm 0.77 (t, J=7.32 Hz, 6H) 1.40 (d, J=7.03 Hz, 3H) 1.83-2.13 (m, 4H) 4.96 (ddd, J=14.65, 7.23, 7.03 Hz, 1H) 5.08 (s, 2H) 7.21 (ddd, J=11.57, 8.93, 7.62 Hz, 1H) 7.35-7.41 (m, 4H) 7.45 (ddd, J=8.84, 3.86, 0.78 Hz, 1H) 8.19-8.22 (m, 1H) 8.83 (d, J=8.01 Hz, 1H); MS [M+H], calcd: 411.0, found: 411.3.
