Reaction Steps
Using the method in Example 154, this compound was prepared from methyl 4-(2-hydroxy-5-oxo-5,6,7,8-tetrahydro-1-naphthalenyl)methylsulfonylbenzoate (1.98 g, 5.3 mmol), (R)-2-imidazol-1-yl-1-phenylethanol (1.00 g, 5.3 mmol), Ph3P (2.10 g, 8.0 mmol), and diethyl azodicarboxylate (1.39 g, 8.0 mmol) as a solid-foam, 2.78 g, 96% yield; mp 105° C. NMR spectrum was consistent with structure. Calcd. For C30H28N2O6S.H2O:
