実験手順

Reflux a mixture of 2-[1,4]diazepan-1-yl-1-(2-pyrazol-1-yl-ethyl)-1H-benzoimidazole dihydroiodide (0.48 g, 0.84 mmol), methanesulfonic acid 2-{(S)-1-[1-(2-methoxy-5-tetrazol-1-yl-phenyl)-methanoyl]-3-phenyl-pyrrolidin-3-yl}-ethyl ester (0.40 g, 0.84 mmol, example 47.2), diisopropylethylamine (0.44 g, 3.37 mmol) and acetonitrile (20 mL) for 12 hours. Cool and dilute with dichloromethane (150 mL), wash the organic phase with water (2×10 mL), dry (MgSO4) the organic phase, filter and evaporate. Purify the residue by silica gel chromatography eluting with 0.5% methanol in dichloromethane to afford 0.29 g of the title compound, Rf=0.18 (silica gel, 0.5% methanol in dichloromethane). The compound may be converted to the dihydrochloride salt by methods well known in the art.
