Reaction Steps

A mixture of 4-(5-{2-ethoxy-5-methyl-1-[3-(trifluoromethyl)phenyl]-1H-imidazol-4-yl}-1H-pyrazol-1-yl)benzonitrile (intermediate 5) (66 mg, 0.15 mmol) and 1-bromo-3-methanesulfonyl propane (201 mg, 1.0 mmol) in acetonitrile (0.20 mL) was heated at 120° C. for 6 h. The mix was cooled to RT and diluted with acetonitrile (2 mL) and water (1 mL) then treated with 1M sodium hydroxide (0.20 ml). The mixture was heated at 50° C. for 2 h. The cold mixture was diluted with water (10 mL) and extracted with EtOAc (2×10 mL). The combined organic phase was dried (sodium sulfate) and concentrated in vacuo. The residue was purified by MDAP to afford the title compound (10 mg).
