Using 4-(2-benzyloxy-ethyl)-2-(4-bromo-2-fluoro-phenyl)-5-methyl-oxazole (see Intermediate 37) and 4-methylsulfonylphenylboronic acid, follow a procedure in substantial accordance with that found in Example 4. Take this product and hydrogenate using 20% palladium hydroxide on carbon in tetrahydrofuran for 36 hours at 40° C. and 60 psi. After this time, filter the reaction and concentrate in vacuo. Purify via radial chromatography eluting with methanol and dichloromethane. MS (m/e): 376.2 (M+1)
