Reaction Steps

2-[3-(3-ethyl-1-methyl-2-oxo-azepan-3-yl)-phenoxy]-4-(1-trityl-1H-imidazol-4-ylmethyl)-benzonitrile (as described in Example 15, Step B) (0.074 g, 0.110 mmol) and triethylsilane (0.140 mL, 0.828 mmol) were stirred in CH2Cl2 (5 mL) and TFA (2.5 mL) for 1 h. The solution was concentrated in vacuo and purified using reverse phase chromatography (95/5-5/95 H2O/CH3CN with 0.1% TFA, flow=65 mL/min). The compound was converted to its free base using saturated NaHCO3 solution, extracted with CH2Cl2 (3×), dried (MgSO4), filtered and treated with 1N HCl ethereal solution to give the title compound.
