Participants

Reaction Steps

A solution of {5-[1-(4-cyano-3-fluorophenyl)-1-hydroxyethyl]imidazol-1-yl}acetic acid, lithium salt from Step H (40 mg, 0.145 mmol), 1-amino-2-(3′-hydroxybiphenyl-2-yl)ethane from Example 6, Step C (33 mg, 0.155 mmol), 1-hydroxybenzotriazole hydrate (23 mg, 0.17 mmol), EDC (33 mg, 0.17 mmol), and N,N-diisopropylethylamine (40 mg, 0.31 mmol) in dry, degassed DMF (1 mL) was stirred at ambient temperature for 18 hrs. The solvent was removed under reduced pressure and the residue was partitioned between sat. aq. NaHCO3 (1 mL) and CHCl3 (3 mL). The aqueous layer was extracted further with CHCl3 (2×2 mL). The combined organic extracts were dried over Na2SO4, filtered, and concentrated under reduced pressure. The crude product was purified by preparative thin layer chromatography, eluting with 6% MeOH/0.6% NH4OH in CH2Cl2 to give the titled product as a white solid.
