Procedure

Using essentially the same procedure as Example 25, Step B, but using CBZ-Cl (0.030 mL, 1.2 mmol) in Step B, 4,5-di-(4-chlorophenyl)-1-(2-(trimethylsilyl)ethoxymethyl)imidazole (31 mg, 0.074 mmol) from Example 25, Step A was converted to the title compound. HPLC/MS: 553 (M+1), 555 (M+3); Rt=5.2 min.
