Procedure
Using the K2CO3 /acetone conditions for phenol alkylation described in Step A of Example 4; 5,7-dimethyl-2-ethyl-3-[4-hydroxy-3-propylphenyl methyl]-3H-imidazo[4,5-b]pyridine (Step A, Example 8) was alkylated with methyl 2-bromo-2-(4-chlorophenyl)acetate. Standard workup and purification by flash chromatography afforded a 50% yield of the title compound.
