Procedure

Using essentially the same procedure as Example 25, Step B-C, but using t-butyl isocyanate (0.016 mL, 0.14 mmol) in Step B, 4,5-di-(4-chlorophenyl)-1-(2-(trimethylsilyl)ethoxymethyl)imidazole (23 mg, 0.055 mmol) from Example 25, Step A was converted to the SEM intermediate and then to the title compound with TBAF.
